Population density is a measurement of population per unit area or unit volume. It is applied to living organisms, most of the time to humans, it is a key geographical term. In simple terms population density refers to the number of people living in an area per kilometer square. Population density is population divided by total land water volume, as appropriate. Low densities may lead to further reduced fertility; this is called the Allee effect after the scientist. Examples of the causes in low population densities include: Increased problems with locating sexual mates Increased inbreeding For humans, population density is the number of people per unit of area quoted per square kilometer or square mile; this may be calculated for a county, country, another territory or the entire world. The world's population is around 7,500,000,000 and Earth's total area is 510,000,000 square kilometers. Therefore, the worldwide human population density is around 7,500,000,000 ÷ 510,000,000 = 14.7 per km2. If only the Earth's land area of 150,000,000 km2 is taken into account human population density is 50 per km2.
This includes all continental and island land area, including Antarctica. If Antarctica is excluded population density rises to over 55 people per km2. However, over half of the Earth's land mass consists of areas inhospitable to human habitation, such as deserts and high mountains, population tends to cluster around seaports and fresh-water sources. Thus, this number by itself does not give any helpful measurement of human population density. Several of the most densely populated territories in the world are city-states and dependencies; these territories have a small area and a high urbanization level, with an economically specialized city population drawing on rural resources outside the area, illustrating the difference between high population density and overpopulation The potential to maintain the agricultural aspects of deserts is limited as there is not enough precipitation to support a sustainable land. The population in these areas are low. Therefore, cities in the Middle East, such as Dubai, have been increasing in population and infrastructure growth at a fast pace.
Cities with high population densities are, by some, considered to be overpopulated, though this will depend on factors like quality of housing and infrastructure and access to resources. Most of the most densely populated cities are in Southeast Asia, though Cairo and Lagos in Africa fall into this category. City population and area are, however dependent on the definition of "urban area" used: densities are invariably higher for the central city area than when suburban settlements and the intervening rural areas are included, as in the areas of agglomeration or metropolitan area, the latter sometimes including neighboring cities. For instance, Milwaukee has a greater population density when just the inner city is measured, the surrounding suburbs excluded. In comparison, based on a world population of seven billion, the world's inhabitants, as a loose crowd taking up ten square feet per person, would occupy a space a little larger than Delaware's land area; the Gaza Strip has a population density of 5,046 pop/km.
Although arithmetic density is the most common way of measuring population density, several other methods have been developed to provide a more accurate measure of population density over a specific area. Arithmetic density: The total number of people / area of land Physiological density: The total population / area of arable land Agricultural density: The total rural population / area of arable land Residential density: The number of people living in an urban area / area of residential land Urban density: The number of people inhabiting an urban area / total area of urban land Ecological optimum: The density of population that can be supported by the natural resources Demography Human geography Idealized population Optimum population Population genetics Population health Population momentum Population pyramid Rural transport problem Small population size Distance sampling List of population concern organizations List of countries by population density List of cities by population density List of city districts by population density List of English districts by population density List of European cities proper by population density List of United States cities by population density List of islands by population density List of U.

2000 United States presidential election
The 2000 United States presidential election was the 54th quadrennial presidential election. It was held on Tuesday, November 7, 2000. Republican candidate George W. Bush, the Governor of Texas and the eldest son of the 41st President George H. W. Bush, won the election by defeating Democratic nominee Al Gore, the incumbent vice president, it was the fourth of five presidential elections in which the winning candidate lost the popular vote, is considered one of the closest elections in US history. Vice President Gore secured the Democratic nomination with relative ease, defeating a challenge by former Senator Bill Bradley. Bush was seen as the early favorite for the Republican nomination and, despite a contentious primary battle with Senator John McCain and other candidates, secured the nomination by Super Tuesday. Bush chose former Secretary of Defense Dick Cheney as his running mate, while Gore chose Senator Joe Lieberman as his; the left-wing Green Party nominated a ticket consisting of political activists Ralph Nader and Winona LaDuke.
Both major party candidates focused on domestic issues, such as the budget, tax relief, reforms for federal social insurance programs, although foreign policy was not ignored. Due to Clinton's sex scandal with Monica Lewinsky and subsequent impeachment, Gore avoided campaigning with Clinton. Republicans denounced Clinton's indiscretions. On election night, it was unclear who had won, with the electoral votes of the state of Florida still undecided; the returns showed that Bush had won Florida by such a close margin that state law required a recount. A month-long series of legal battles led to the contentious, 5–4 Supreme Court decision of Bush v. Gore, which ended the recount. With the end of the recount, Bush won Florida by a margin of or 537 votes; the Florida recount and subsequent litigation resulted in a major post-election controversy, various individuals and organizations have speculated about who would have won the election in various scenarios. Bush won 271 electoral votes, one more than was necessary for the majority, despite Gore receiving 543,895 more votes.
Article Two of the United States Constitution provides that the President and Vice President of the United States must be natural-born citizens of the United States, at least 35 years old, a resident of the United States for a period of at least 14 years. Candidates for the presidency seek the nomination of one of the political parties of the United States, in which case each party devises a method to choose the candidate the party deems best suited to run for the position. Traditionally, the primary elections are indirect elections where voters cast ballots for a slate of party delegates pledged to a particular candidate; the party's delegates officially nominate a candidate to run on the party's behalf. The general election in November is an indirect election, where voters cast ballots for a slate of members of the Electoral College. President Bill Clinton, a Democrat and former Governor of Arkansas, was ineligible to seek reelection to a third term due to restrictions of the Twenty-second Amendment.
In accordance with Section I of the Twentieth Amendment, his term expired at 12:00 noon EST on January 20, 2001. Democratic candidates Al Gore, Vice President of the United States Bill Bradley, former U. S. Senator from Connecticut Al Gore from Tennessee was a consistent front-runner for the nomination. Other prominent Democrats mentioned as possible contenders included Bob Kerrey, Missouri Representative Dick Gephardt, Minnesota Senator Paul Wellstone, famous actor and director Warren Beatty, who declined to run. Of these, only Wellstone formed an exploratory committee. Running an insurgency campaign, Bradley positioned himself as the alternative to Gore, a founding member of the centrist Democratic Leadership Council. While former basketball star Michael Jordan campaigned for him in the early primary states, Bradley announced his intention to campaign "in a different way" by conducting a positive campaign of "big ideas"; the focus of his campaign was a plan to spend the record-breaking budget surplus on a variety of social welfare programs to help the poor and the middle-class, along with campaign finance reform and gun control.
Gore defeated Bradley in the primaries because of support from the Democratic Party establishment and Bradley's poor showing in the Iowa caucus, where Gore painted Bradley as aloof and indifferent to the plight of farmers. The closest Bradley came to a victory was his 50–46 loss to Gore in the New Hampshire primary. On March 14, Al Gore clinched the Democratic nomination. None of Bradley's delegates were allowed to vote for him, so Gore won the nomination unanimously at the Democratic National Convention. Connecticut Senator Joe Lieberman was nominated for vice president by voice vote. Lieberman became the first Jewish American to be chosen for this position by a major party. Gore chose Lieberman over five other finalists: Senators Evan Bayh, John Edwards, John Kerry, House Minority Leader Dick Gephardt, New Hampshire Governor Jeanne Shaheen. Delegate totals: Vice President Albert Gore Jr. 4328 Abstentions 9 Republican candidates John McCain, Senator from Arizona Alan Keyes, former U. S. ECOSOC Ambassador from Maryland Steve Forbes, businessman from New Jersey Gary Bauer, former Undersecretary of Education from Kentucky (withd
Florida is the southernmost contiguous state in the United States. The state is bordered to the west by the Gulf of Mexico, to the northwest by Alabama, to the north by Georgia, to the east by the Atlantic Ocean, to the south by the Straits of Florida. Florida is the 22nd-most extensive, the 3rd-most populous, the 8th-most densely populated of the U. S. states. Jacksonville is the most populous municipality in the state and the largest city by area in the contiguous United States; the Miami metropolitan area is Florida's most populous urban area. Tallahassee is the state's capital. Florida's $1.0 trillion economy is the fourth largest in the United States. If it were a country, Florida would be the 16th largest economy in the world, the 58th most populous as of 2018. In 2017, Florida's per capita personal income was ranking 26th in the nation; the unemployment rate in September 2018 was 3.5% and ranked as the 18th in the United States. Florida exports nearly $55 billion in goods made in the 8th highest among all states.
The Miami Metropolitan Area is by far the largest urban economy in Florida and the 12th largest in the United States with a GDP of $344.9 billion as of 2017. This is more than twice the number of the next metro area, the Tampa Bay Area, which has a GDP of $145.3 billion. Florida is home to 51 of the world's billionaires with most of them residing in South Florida; the first European contact was made in 1513 by Spanish explorer Juan Ponce de León, who called it la Florida upon landing there in the Easter season, known in Spanish as Pascua Florida. Florida was a challenge for the European colonial powers before it gained statehood in the United States in 1845, it was a principal location of the Seminole Wars against the Native Americans, racial segregation after the American Civil War. Today, Florida is distinctive for its large Cuban expatriate community and high population growth, as well as for its increasing environmental issues; the state's economy relies on tourism and transportation, which developed in the late 19th century.
Florida is renowned for amusement parks, orange crops, winter vegetables, the Kennedy Space Center, as a popular destination for retirees. Florida is the flattest state in the United States. Lake Okeechobee is the largest freshwater lake in the U. S. state of Florida. Florida's close proximity to the ocean influences many aspects of daily life. Florida is a reflection of multiple inheritance. Florida has attracted many writers such as Marjorie Kinnan Rawlings, Ernest Hemingway and Tennessee Williams, continues to attract celebrities and athletes, it is internationally known for golf, auto racing, water sports. Several beaches in Florida have emerald-colored coastal waters. About two-thirds of Florida occupies a peninsula between the Gulf of the Atlantic Ocean. Florida has the longest coastline in the contiguous United States 1,350 miles, not including the contribution of the many barrier islands. Florida has a total of 4,510 islands; this is the second-highest number of islands of any state of the United States.
It is the only state that borders both the Gulf of the Atlantic Ocean. Much of the state is characterized by sedimentary soil. Florida has the lowest high point of any U. S. state. The climate varies from subtropical in the north to tropical in the south; the American alligator, American crocodile, American flamingo, Roseate spoonbill, Florida panther, bottlenose dolphin, manatee can be found in Everglades National Park in the southern part of the state. Along with Hawaii, Florida is one of only two states that has a tropical climate, is the only continental state with either a tropical climate or a coral reef; the Florida Reef is the only living coral barrier reef in the continental United States, the third-largest coral barrier reef system in the world. By the 16th century, the earliest time for which there is a historical record, major Native American groups included the Apalachee of the Florida Panhandle, the Timucua of northern and central Florida, the Ais of the central Atlantic coast, the Tocobaga of the Tampa Bay area, the Calusa of southwest Florida and the Tequesta of the southeastern coast.
Florida was the first region of the continental United States to be visited and settled by Europeans. The earliest known European explorers came with the Spanish conquistador Juan Ponce de León. Ponce de León spotted and landed on the peninsula on April 2, 1513, he named the region Florida. The story that he was searching for the Fountain of Youth is mythical and only appeared long after his death. In May 1539, Conquistador Hernando de Soto skirted the coast of Florida, searching for a deep harbor to land, he described seeing a thick wall of red mangroves spread mile after mile, some reaching as high as 70 feet, with intertwined and elevated roots making landing difficult. The Spanish introduced Christianity, horses, the Castilian language, more to Florida. Spain established several settlements with varying degrees of success. In 1559, Don Tristán de Luna y Arellano established a settlement at present-day Pensacola, making it the first attempted settlement in Florida, but it was abandoned by 1561.
In 1565, the settlement of St. Augustine was established under the leadership of admiral and
2012 United States presidential election
The 2012 United States presidential election was the 57th quadrennial American presidential election, held on Tuesday, November 6, 2012. The Democratic nominee, President Barack Obama, his running mate, Vice President Joe Biden, were elected to a second term, they defeated the Republican ticket of former Governor Mitt Romney of Massachusetts and Representative Paul Ryan of Wisconsin. As the incumbent president, Obama secured the Democratic nomination with no serious opposition; the Republicans experienced a competitive primary. Romney was competitive in the polls and won the support of many party leaders, but he faced challenges from a number of more conservative contenders. Romney clinched his party's nomination in May, defeating Rick Santorum, Newt Gingrich, several other candidates; the campaigns focused on domestic issues, debate centered around sound responses to the Great Recession. Other issues included long-term federal budget issues, the future of social insurance programs, the Affordable Care Act, Obama's marquee legislative program.
Foreign policy was discussed, including the phase-out of the Iraq War, military spending, the Iranian nuclear program, appropriate counteractions to terrorism. The campaign was marked by a sharp rise in fundraising, including from nominally independent Super PACs. Obama defeated Romney, winning a majority of both the Electoral College. Obama won 51.1% of the popular vote compared to Romney's 47.2%. Obama was the first incumbent since Franklin D. Roosevelt in 1944 to win reelection with fewer electoral votes and a lower popular vote percentage than had been won in the previous election, was the first two-term president since Ronald Reagan to win both his presidential bids with a majority of the nationwide popular vote. In 2011, several state legislatures passed new voting laws pertaining to voter identification, with the stated purpose of combating voter fraud. Florida, Ohio and West Virginia's state legislatures approved measures to shorten early voting periods. Florida and Iowa barred all felons from voting.
Kansas, South Carolina, Tennessee and Wisconsin state legislatures passed laws requiring voters to have government-issued IDs before they could cast their ballots. This meant that people without driver's licenses or passports had to gain new forms of ID. Obama, the NAACP, the Democratic Party fought against many of the new state laws. Former President Bill Clinton denounced them, saying, "There has never been in my lifetime, since we got rid of the poll tax and all the Jim Crow burdens on voting, the determined effort to limit the franchise that we see today", he was referring to Jim Crow laws passed in southern states near the turn of the twentieth century that disenfranchised most blacks from voting and excluded them from the political process for more than six decades. Clinton said the moves would disenfranchise core voter blocs that trend liberal, including college students and Latinos. Rolling Stone magazine criticized the American Legislative Exchange Council for lobbying in states to bring about these laws, to "solve" a problem that does not exist.
The Obama campaign fought against the Ohio law, pushing for a petition and statewide referendum to repeal it in time for the 2012 election. In addition, the Pennsylvania legislature proposed a plan to change its representation in the electoral college from the traditional winner-take-all model to a district-by-district model; as the governorship and both houses of its legislature were Republican-controlled, the move was viewed by some as an attempt to reduce Democratic chances. With an incumbent president running for re-election against token opposition, the race for the Democratic nomination was uneventful; the nomination process consisted of primaries and caucuses, held by the 50 states, as well as Guam, Puerto Rico, Washington, D. C. U. S. Virgin Islands, American Samoa, Democrats Abroad. Additionally, high-ranking party members known as superdelegates each received one vote in the convention. A few of the primary challengers surpassed the president's vote total in individual counties in several of the seven contested primaries, though none made a significant impact in the delegate count.
Running unopposed everywhere else, President Obama cemented his status as the Democratic presumptive nominee on April 3, 2012, by securing the minimum number of pledged delegates needed to obtain the nomination. Candidates with considerable name recognition who entered the race for the Republican presidential nomination in the early stages of the primary campaign included Representative and former Libertarian nominee Ron Paul, former Minnesota Governor Tim Pawlenty, who co-chaired John McCain's campaign in 2008, former Massachusetts Governor Mitt Romney, the runner-up for the nomination in the 2008 cycle, former Speaker of the House Newt Gingrich; the first debate took place on May 5, 2011, in Greenville, South Carolina, with businessman Herman Cain, former New Mexico Governor Gary Johnson, Ron Paul, Tim Pawlenty, former Pennsylvania Senator Rick Santorum participating. Another debate took place a month with Newt Gingrich, Mitt Romney, former Utah Governor Jon Huntsman, Rep. Michele Bachmann participating, Gary Johnson excluded.
A total of thirteen debates were held before the Iowa caucuses. The first major event of the campaign was the Ames Straw Poll, which took place in Iowa on August 13, 2011. Michele Bachmann won the straw poll. Pawlenty withdrew from the race after a poor showin
2010 United States Census
The 2010 United States Census is the twenty-third and most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010; the census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired; the population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census. This was the first census in which all states recorded a population of over half a million, as well as the first in which all 100 largest cities recorded populations of over 200,000; as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed. Participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25, 2010, Census Bureau Director Robert Groves inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, a resident of Noorvik, Alaska.
More than 120 million census forms were delivered by the U. S. Post Office beginning March 15, 2010; the number of forms mailed out or hand-delivered by the Census Bureau was 134 million on April 1, 2010. Although the questionnaire used April 1, 2010 as the reference date as to where a person was living, an insert dated March 15, 2010 included the following printed in bold type: "Please complete and mail back the enclosed census form today." The 2010 Census national mail participation rate was 74%. From April through July 2010, census takers visited households that did not return a form, an operation called "non-response follow-up". In December 2010, the U. S. Census Bureau delivered population information to the U. S. President for apportionment, in March 2011, complete redistricting data was delivered to states. Identifiable information will be available in 2082; the Census Bureau did not use a long form for the 2010 Census. In several previous censuses, one in six households received this long form, which asked for detailed social and economic information.
The 2010 Census used only a short form asking ten basic questions: How many people were living or staying in this house, apartment, or mobile home on April 1, 2010? Were there any additional people staying here on April 1, 2010 that you did not include in Question 1? Mark all that apply: Is this house, apartment, or mobile home – What is your telephone number? What is Person 1's name? What is Person 1's sex? What is Person 1's age and Person 1's date of birth? Is Person 1 of Hispanic, Latino, or Spanish origin? What is Person 1's race? Does Person 1 sometimes live or stay somewhere else? The form included space to repeat all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, nor was the form available for download. Detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey; the survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years.
A small percentage of the population on a rotating basis will receive the survey each year, no household will receive it more than once every five years. In June 2009, the U. S. Census Bureau announced. However, the final form did not contain a separate "same-sex married couple" option; when noting the relationship between household members, same-sex couples who are married could mark their spouses as being "Husband or wife", the same response given by opposite-sex married couples. An "unmarried partner" option was available for couples; the 2010 census cost $13 billion $42 per capita. Operational costs were $5.4 billion under the $7 billion budget. In December 2010 the Government Accountability Office noted that the cost of conducting the census has doubled each decade since 1970. In a detailed 2004 report to Congress, the GAO called on the Census Bureau to address cost and design issues, at that time, had estimated the 2010 Census cost to be $11 billion. In August 2010, Commerce Secretary Gary Locke announced that the census operational costs came in under budget.
Locke credited the management practices of Census Bureau director Robert Groves, citing in particular the decision to buy additional advertising in locations where responses lagged, which improved the overall response rate. The agency has begun to rely more on questioning neighbors or other reliable third parties when a person could not be reached at home, which reduced the cost of follow-up visits. Census data for about 22% of U. S. househol
A census is the procedure of systematically acquiring and recording information about the members of a given population. The term is used in connection with national population and housing censuses; the United Nations defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory and defined periodicity", recommends that population censuses be taken at least every 10 years. United Nations recommendations cover census topics to be collected, official definitions and other useful information to co-ordinate international practice; the word is of Latin origin: during the Roman Republic, the census was a list that kept track of all adult males fit for military service. The modern census is essential to international comparisons of any kind of statistics, censuses collect data on many attributes of a population, not just how many people there are. Censuses began as the only method of collecting national demographic data, are now part of a larger system of different surveys.
Although population estimates remain an important function of a census, including the geographic distribution of the population, statistics can be produced about combinations of attributes e.g. education by age and sex in different regions. Current administrative data systems allow for other approaches to enumeration with the same level of detail but raise concerns about privacy and the possibility of biasing estimates. A census can be contrasted with sampling in which information is obtained only from a subset of a population. Modern census data are used for research, business marketing, planning, as a baseline for designing sample surveys by providing a sampling frame such as an address register. Census counts are necessary to adjust samples to be representative of a population by weighting them as is common in opinion polling. Stratification requires knowledge of the relative sizes of different population strata which can be derived from census enumerations. In some countries, the census provides the official counts used to apportion the number of elected representatives to regions.
In many cases, a chosen random sample can provide more accurate information than attempts to get a population census. A census is construed as the opposite of a sample as its intent is to count everyone in a population rather than a fraction. However, population censuses rely on a sampling frame to count the population; this is the only way to be sure that everyone has been included as otherwise those not responding would not be followed up on and individuals could be missed. The fundamental premise of a census is that the population is not known and a new estimate is to be made by the analysis of primary data; the use of a sampling frame is counterintuitive as it suggests that the population size is known. However, a census is used to collect attribute data on the individuals in the nation; this process of sampling marks the difference between historical census, a house to house process or the product of an imperial decree, the modern statistical project. The sampling frame used by census is always an address register.
Thus it is not known how many people there are in each household. Depending on the mode of enumeration, a form is sent to the householder, an enumerator calls, or administrative records for the dwelling are accessed; as a preliminary to the dispatch of forms, census workers will check any address problems on the ground. While it may seem straightforward to use the postal service file for this purpose, this can be out of date and some dwellings may contain a number of independent households. A particular problem is what are termed'communal establishments' which category includes student residences, religious orders, homes for the elderly, people in prisons etc; as these are not enumerated by a single householder, they are treated differently and visited by special teams of census workers to ensure they are classified appropriately. Individuals are counted within households and information is collected about the household structure and the housing. For this reason international documents refer to censuses of housing.
The census response is made by a household, indicating details of individuals resident there. An important aspect of census enumerations is determining which individuals can be counted from which cannot be counted. Broadly, three definitions can be used: de facto residence; this is important to consider individuals who have temporary addresses. Every person should be identified uniquely as resident in one place but where they happen to be on Census Day, their de facto residence, may not be the best place to count them. Where an individual uses services may be more useful and this is at their usual, or de jure, residence. An individual may be represented at a permanent address a family home for students or long term migrants, it is necessary to have a precise definition of residence to decide whether visitors to a country should be included in the population count. This is becoming more important as students travel abroad for education for a period of several years. Other groups causing problems of enumeration are new born babies, people away on holiday, people moving home around census day, people without a fixed address.
People having second homes because of working in another part of the country or retaining a holiday cottage are dif
Hillsborough County, Florida
Hillsborough County is a county in the U. S. state of Florida. In the 2010 census, the population was 1,229,226, making it the fourth-most populous county in Florida and the most populous county outside the Miami Metropolitan Area. A 2017 estimate has the population of Hillsborough County at 1,408,566 people, which itself is greater than the populations of 10 states according to their 2017 population estimates, its county seat and largest city is Tampa. Hillsborough County is part of the Tampa–St. Petersburg–Clearwater Metropolitan Statistical Area. Hillsborough County was created on January 25, 1834, from Alachua and Monroe Counties, during the U. S. territorial period. The new county was named for Wills Hill, the Earl of Hillsborough, who served as British Secretary of State for the Colonies from 1768 to 1772; the County was created through efforts by Augustus Steele. The county's 1834 area was much larger and included eight other present-day counties: Charlotte County, DeSoto, Manatee, Pinellas and Sarasota.
The last significant change in Hillsborough County's borders was the separation of its western section to create Pinellas County in 1911. On New Year's Day in 1914, the St. Petersburg-Tampa Airboat Line initiated the first scheduled commercial airline service in the world, from St. Petersburg to Tampa. According to the U. S. Census Bureau, the county has a total area of 1,266 square miles, of which 1,020 square miles are land and 246 square miles are covered by water. About 158.27 miles of shoreline are on Tampa Bay. The county's unincorporated area is more than 84 % of the total land area. Municipalities account for 163 square miles; the modern boundaries of the county place it midway along the west coast of Florida. A narrow portion of Hillsborough County to the south, consisting exclusively of water, extends west to the Gulf of Mexico along the Tampa Port Shipping Channel; this has the effect of keeping Hillsborough County from being technically landlocked. The central portion of the Sunshine Skyway Bridge is in Hillsborough County.
So is Egmont Key, at the entrance to Tampa Bay. The northernmost tip of a spoil island just west of Port Manatee lies in Hillsborough County. Hillsborough is home to Alafia River State Park and Hillsborough River state parks, to the C. W. Bill Young Regional Reservoir and Lithia Springs, one of the largest natural springs in Florida.

About 27.12% of all households were made up of individuals and 7.96% had someone living alone, 65 years of age or older. The average household size was 2.55 and the average family size was 3.11. The age distribution was 23.9% under the age of 18, 10.5% from 18 to 24, 28.3% from 25 to 44, 25.4% from 45 to 64, 11.8% were 65 years of age or older. The median age was 36.1 years. For every 100 females, there were 95.1 males. For every 100 females age 18 and over, there were 92.1 males. The median income for a household in the county was $49,536, for a family was $59,886. Males had a median income of $43,125 versus $35,184 for females; the per capita income for the county was $27,062. About 10.7% of families and 14.2% of the population were below the poverty line, including 19.9% of those under age 18 and 9.6% of those aged 65 or over. In 2010, 15.1% of the county's population was foreign born, with 44.5% being naturalized American citizens. Of foreign-born residents, 67.5% were born in Latin America, 16.7% born in Asia, 9.2% were born in Europe, 3.2% born in Africa, 3.1% in North America, 0.3% were born in Oceania.
