A Mediterranean climate or dry summer climate is characterized by rainy winters and dry summers, with less than 40 mm of precipitation for at least three summer months. While the climate receives its name from the Mediterranean Basin, these are located on the western coasts of continents, between 30 and 45 degrees north and south of the equator between oceanic climates towards the poles, semi-arid and arid climates towards the equator. In essence, due to the seasonal shift of the subtropical high-pressure belts with the apparent movement of the Sun, a Mediterranean climate is an intermediate type between these other climates, with winters warmer and drier than oceanic climates and summers imitating sunny weather in semi-arid and arid climates; the resulting vegetation of Mediterranean climates are the garrigue or maquis in the Mediterranean Basin, the chaparral in California, the fynbos in South Africa, the mallee in Australia, the matorral in Chile. Areas with this climate are where the so-called "Mediterranean trinity" of agricultural products have traditionally developed: wheat and olive.
Most large, historic cities of the Mediterranean basin lie within Mediterranean climatic zones, including Algiers, Beirut, İzmir, Marseille, Rome and Valencia. Examples of major cities with Mediterranean climates that lie outside of the historic Mediterranean basin include major examples as Adelaide, Cape Town, Dushanbe, Los Angeles, Perth, San Francisco and Victoria. Under the Köppen climate classification, "hot dry-summer" climates and "cool dry-summer" climates are referred to as "Mediterranean". Under the Köppen climate system, the first letter indicates the climate group. Temperate climates or "C" zones have an average temperature above 0 °C, but below 18 °C, in their coolest months; the second letter indicates the precipitation pattern. Köppen has defined a dry summer month as a month with less than 30 mm of precipitation and with less than one-third that of the wettest winter month. Some, use a 40 mm level; the third letter indicates the degree of summer heat: "a" represents an average temperature in the warmest month above 22 °C, while "b" indicates the average temperature in the warmest month below 22 °C.
Under the Köppen classification, dry-summer climates occur on the western sides of continents. Csb zones in the Köppen system include areas not associated with Mediterranean climates but with Oceanic climates, such as much of the Pacific Northwest, much of southern Chile, parts of west-central Argentina, parts of New Zealand. Additional highland areas in the subtropics meet Cs requirements, though they, are not associated with Mediterranean climates, as do a number of oceanic islands such as Madeira, the Juan Fernández Islands, the western part of the Canary Islands, the eastern part of the Azores. Under Trewartha's modified Köppen climate classification, the two major requirements for a Cs climate are revised. Under Trewartha's system, at least eight months must have average temperatures of 10 °C or higher, the average annual precipitation must not exceed 900 mm. Thus, under this system, many Csb zones in the Köppen system become Do, the rare Csc zones become Eo, with only the classic dry-summer to warm winter, low annual rainfall locations included in the Mediterranean type climate.
During summer, regions of Mediterranean climate are influenced by cold ocean currents which keep the weather in the region dry and pleasant. Similar to desert climates, in many Mediterranean climates there is a strong diurnal character to daily temperatures in the warm summer months due to strong heating during the day from sunlight and rapid cooling at night. In winter, Mediterranean climate zones are no longer influenced by the cold ocean currents and therefore warmer water settles near land and causes clouds to form and rainfall becomes much more likely; as a result, areas with this climate receive all of their precipitation during their winter and spring seasons, may go anywhere from 3 to 6 months during the summer without having any significant precipitation. In the lower latitudes, precipitation decreases in both the winter and summer because they are closer to the Horse latitudes, thus bringing smaller amounts of rain. Toward the polar latitudes, total moisture increases; the rainfall tends to be more evenly distributed throughout the year in Southern Europe, while in the Eastern Mediterranean and in Southern California the summer is nearly or dry.
In places where evapotranspiration is higher, steppe climates tend to prevail, but still follow the weather pattern of the Mediterranean climate. The majority of the regions with Mediterranean climates have mild winters and warm summers; however winter and summer temperatures can vary between different regions with a Mediterranean climate. For instance, in the case of winters and Los Angeles experience mild temperatures in the winter, with frost and snowfall unknown, whereas Tashkent has colder winters with annual frosts and snowfall. Or to consider summer, Athens experiences rather high temperatures in that season. In contrast, San Francisco has cool summers with daily highs around 21 °C due to
United States Census Bureau
The United States Census Bureau is a principal agency of the U. S. Federal Statistical System, responsible for producing data about the American people and economy; the Census Bureau is part of the U. S. Department of Commerce and its director is appointed by the President of the United States; the Census Bureau's primary mission is conducting the U. S. Census every ten years, which allocates the seats of the U. S. House of Representatives to the states based on their population; the Bureau's various censuses and surveys help allocate over $400 billion in federal funds every year and it helps states, local communities, businesses make informed decisions. The information provided by the census informs decisions on where to build and maintain schools, transportation infrastructure, police and fire departments. In addition to the decennial census, the Census Bureau continually conducts dozens of other censuses and surveys, including the American Community Survey, the U. S. Economic Census, the Current Population Survey.
Furthermore and foreign trade indicators released by the federal government contain data produced by the Census Bureau. Article One of the United States Constitution directs the population be enumerated at least once every ten years and the resulting counts used to set the number of members from each state in the House of Representatives and, by extension, in the Electoral College; the Census Bureau now conducts a full population count every 10 years in years ending with a zero and uses the term "decennial" to describe the operation. Between censuses, the Census Bureau makes population projections. In addition, Census data directly affects how more than $400 billion per year in federal and state funding is allocated to communities for neighborhood improvements, public health, education and more; the Census Bureau is mandated with fulfilling these obligations: the collecting of statistics about the nation, its people, economy. The Census Bureau's legal authority is codified in Title 13 of the United States Code.
The Census Bureau conducts surveys on behalf of various federal government and local government agencies on topics such as employment, health, consumer expenditures, housing. Within the bureau, these are known as "demographic surveys" and are conducted perpetually between and during decennial population counts; the Census Bureau conducts economic surveys of manufacturing, retail and other establishments and of domestic governments. Between 1790 and 1840, the census was taken by marshals of the judicial districts; the Census Act of 1840 established a central office. Several acts followed that revised and authorized new censuses at the 10-year intervals. In 1902, the temporary Census Office was moved under the Department of Interior, in 1903 it was renamed the Census Bureau under the new Department of Commerce and Labor; the department was intended to consolidate overlapping statistical agencies, but Census Bureau officials were hindered by their subordinate role in the department. An act in 1920 changed the date and authorized manufacturing censuses every two years and agriculture censuses every 10 years.
In 1929, a bill was passed mandating the House of Representatives be reapportioned based on the results of the 1930 Census. In 1954, various acts were codified into Title 13 of the US Code. By law, the Census Bureau must count everyone and submit state population totals to the U. S. President by December 31 of any year ending in a zero. States within the Union receive the results in the spring of the following year; the United States Census Bureau defines four statistical regions, with nine divisions. The Census Bureau regions are "widely used...for data collection and analysis". The Census Bureau definition is pervasive. Regional divisions used by the United States Census Bureau: Region 1: Northeast Division 1: New England Division 2: Mid-Atlantic Region 2: Midwest Division 3: East North Central Division 4: West North Central Region 3: South Division 5: South Atlantic Division 6: East South Central Division 7: West South Central Region 4: West Division 8: Mountain Division 9: Pacific Many federal, state and tribal governments use census data to: Decide the location of new housing and public facilities, Examine the demographic characteristics of communities and the US, Plan transportation systems and roadways, Determine quotas and creation of police and fire precincts, Create localized areas for elections, utilities, etc.
Gathers population information every 10 years The United States Census Bureau is committed to confidentiality, guarantees non-disclosure of any addresses or personal information related to individuals or establishments. Title 13 of the U. S. Code establishes penalties for the disclosure of this information. All Census employees must sign an affidavit of non-disclosure prior to employment; the Bureau cannot share responses, addresses or personal information with anyone including United States or foreign government
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.

Stanford University Medical Center
Stanford University Medical Center is a medical complex which includes Stanford Health Care and Stanford Children's Health. It is ranked as one of the best hospitals in the United States and serves as a teaching hospital for the Stanford University School of Medicine. Stanford Health Care is located at 300 Pasteur Drive, California, it is ranked as one of the best hospitals in the United States by US News and World Report and serves as the primary teaching hospital for the Stanford University School of Medicine. The facility, located at the north end of the university campus, includes the main hospital building, Stanford Comprehensive Cancer Center, Blake Wilbur Building, Boswell Building, Hoover Pavilion, an outpatient psychiatry facility; the roof of the main building contains a landing facility and Life Flight helicopter. Stanford Health Care provides both general acute care services and tertiary medical care for patients locally and internationally. Organ transplantation, cancer diagnosis and treatment, cardiovascular medicine and surgery, neurosciences are clinical specialties of worldwide renown.
Among its many achievements, the first combined heart-lung transplant in the world was completed at Stanford University Medical Center in 1981. The hospital plays a key role in the training of other medical professionals, it provides a clinical environment for the medical school’s researchers as they study ways to translate new knowledge into effective patient care. Full-time Stanford faculty and community physicians make up the hospital medical staff. Stanford Hospital is home to a Level I trauma center, it became a trauma center in 1986 and first received American College of Surgeons certification as a Level I trauma center in 1998. The hospital's history began with the foundation of the Stanford Home for Convalescent Children in 1911; when the Stanford Medical School moved south from San Francisco in 1959, the Stanford Hospital was established and was co-owned with the city of Palo Alto. It was renamed; the Beckman Center for Molecular and Genetic Medicine opened in 1989. In 1999, Stanford University approved a $185 million, five-year plan to improve the 40-year-old School of Medicine facility.
The Center for Clinical Sciences Research opened in 2000. The Clark Center for interdisciplinary research and bioengineering opened in 2004. In 2009, the Stanford outpatient clinics, which were running out of expansion room, were relocated to the Stanford Medicine Outpatient Center, a large new site in Redwood City, California occupied by the corporate headquarters of Excite@Home; the buildings were extensively remodeled for medical use to provide facilities the clinics' old homes lacked. For example, the Sleep Disorders Clinic's new sleep lab has thorough soundproofing and can accommodate a few morbidly obese patients; the inpatient facilities remain on the Stanford campus. The Stanford Life Flight program began May 1, 1984. Stanford Life Flight flies in an EC 145 helicopter that can fly under both visual and instrument flight rules, allowing for response to calls in nearly any weather; the aircraft will accommodate two patients with two Flight Nurses, or one patient with up to four caregivers, plus the Pilot.
The hospital's medical staff numbers 1,910 with an additional 850 interns and residents, as well as nearly 1,500 registered nurses and 610 licensed beds. Stanford Clinics, the group practice of most faculty physicians of Stanford University School of Medicine, includes 493 full-time faculty physicians, their areas of expertise range from primary care to the most advanced medical and surgical specialties. Stanford Clinics offer subspecialty service areas. Under the supervision of faculty physicians, Stanford medical students and residents participate in patient care in most specialties; the clinics participate in preferred provider health care programs as well as MediCal. Stanford University Medical Center is world-renowned for its work in cardiovascular medicine and surgery, organ transplantation, neurology and cancer diagnosis and treatment, it hosts 20,000 inpatients yearly. In 2017, Stanford Hospital was ranked by U. S. News & World Report as the 9th-best hospital out of 5,462 medical centers in the United States, third in the West Coast after the UCSF Medical Center and the UCLA Medical Center As of 2018, Stanford received high rankings in the following specialties: The Lucile Packard Children's Hospital was founded in 1991.
It is located at 725 Welch Road, Palo Alto, adjacent to the Stanford campus. In 2007 it was ranked as the #10 best children's hospital in the United States by U. S. News & World Report; this hospital in the CA Healthcare Atlas A project by OSHPD
Palo Alto, California
Palo Alto is a charter city located in the northwest corner of Santa Clara County, United States, in the San Francisco Bay Area. Palo Alto means tall stick in Spanish; the city was established by Leland Stanford Sr. when he founded Stanford University, following the death of his son, Leland Stanford Jr. Palo Alto includes portions of Stanford University and shares its borders with East Palo Alto, Mountain View, Los Altos, Los Altos Hills, Portola Valley, Menlo Park; as of the 2010 census, the city's total resident population is 64,403. Palo Alto is one of the five most expensive cities in the United States to live in and its residents are among the highest educated in the country. Palo Alto is headquarters to a number of high-technology companies, including Hewlett-Packard, Space Systems/Loral, VMware, Ford Research and Innovation Center, PARC, IDEO, Palantir Technologies and Lockheed Martin Advanced Technology Center. Palo Alto has served as an incubator and as headquarters to several other prominent high-technology companies such as Apple, Facebook, Intuit and PayPal.
Prior to the arrival of Europeans, the Ohlone lived on the San Francisco peninsula. The area of modern Palo Alto was first recorded by the 1769 party of Gaspar de Portolà, a 63-man, 200-horse expedition from San Diego to Monterey; the group overshot Monterey in the fog and when they reached modern-day Pacifica, ascended Sweeney Ridge and saw the San Francisco Bay. Portolà descended from Sweeney Ridge southeast down San Andreas Creek to Laguna Creek and the Filoli estate, thence to the San Francisquito Creek watershed camping from November 6–11, 1769 by a tall redwood to be known as El Palo Alto. Thinking the bay was too wide to cross, the group retraced their journey to Monterey, never became aware of the Golden Gate entrance to the Bay. In 1777, Father Junipero Serra established the Mission Santa Clara de Asis, whose northern boundary was San Francisquito Creek and whose lands included modern Palo Alto; the area was under the control of the viceroy of Mexico and under the control of Spain. On November 29, 1777, Pueblo de San Jose de Guadalupe was established by order of the viceroy despite the displeasure of the local mission.
The Mexican War of Independence ending in 1821 led to Mexico becoming an independent country, though San Jose did not recognize rule by the new Mexico until May 10, 1825. Mexico proceeded to grant much of the mission land. During the Mexican–American War, the United States seized Alta California in 1846. Mexican citizens in the area could choose to become United States citizens, their land grants were to be recognized if they chose to do so; the land grant, Rancho Rinconada del Arroyo de San Francisquito, of about 2,230-acre on the lower reaches of San Francisquito Creek was given to Maria Antonia Mesa in 1841. She and her husband Rafael Soto had settled in 1835 near present day Newell and Middlefield roads and sold supplies. In 1839, their daughter María Luisa Soto married John Coppinger, to be, in 1841, the grantee of Rancho Cañada de Raymundo. Upon Coppinger's death in 1847, Maria inherited it and married a visiting boat captain, John Greer. Greer owned a home on the site, now Town & Country Village on Embarcadero and El Camino Real.
Greer Avenue and Court are named for him. To the south of the Sotos, the brothers Secundino and Teodoro Robles in 1849 bought Rancho Rincon de San Francisquito from José Peña, the 1841 grantee; the grant covered the area south of Rancho Rinconada del Arroyo de San Francisquito to more or less present day Mountain View. The grant was bounded on the south by Mariano Castro's Rancho Pastoria de las Borregas grant across San Antonio Road; this became the Robles Rancho, which constitutes about 80% of Palo Alto and Stanford University today. In 1863, it was whittled down in the courts to 6,981 acres. Stories say the grand hacienda was built on the former meager adobe of José Peña near Ferne off San Antonio Road, midway between Middlefield and Alma Street, their hacienda hosted fiestas and bull fights. It was ruined in the 1906 earthquake and its lumber was used to build a large barn nearby, said to have lingered until the early 1950s. On April 10, 1853, 250 acres, comprising the present day Barron Park, Matadero Creek and Stanford Business Park, was sold for $2,000 to Elisha Oscar Crosby, who called his new property Mayfield Farm.
The name of Mayfield was attached to the community that started nearby. On September 23, 1856, the Crosby land was transferred to Sarah Wallis to satisfy a debt he owed her. In 1880, Secundino Robles, father to twenty-nine children, still lived just south of Palo Alto, near the location of the present-day San Antonio Shopping Center in Mountain View. Many of the Spanish names in the Palo Alto area represent the local heritage, descriptive terms and former residents. Pena Court, Miranda Avenue, Foothill Expwy, was the married name of Juana Briones and the name occurs in Courts and Avenues and other street names in Palo Alto and Mountain View in the quadrant where she owned vast areas between Stanford University, Grant Road in Mountain View and west of El Camino Real. Yerba Buena was to her credit. Rinconada wa
African Americans are an ethnic group of Americans with total or partial ancestry from any of the black racial groups of Africa. The term refers to descendants of enslaved black people who are from the United States. Black and African Americans constitute the third largest racial and ethnic group in the United States. Most African Americans are descendants of enslaved peoples within the boundaries of the present United States. On average, African Americans are of West/Central African and European descent, some have Native American ancestry. According to U. S. Census Bureau data, African immigrants do not self-identify as African American; the overwhelming majority of African immigrants identify instead with their own respective ethnicities. Immigrants from some Caribbean, Central American and South American nations and their descendants may or may not self-identify with the term. African-American history starts in the 16th century, with peoples from West Africa forcibly taken as slaves to Spanish America, in the 17th century with West African slaves taken to English colonies in North America.
After the founding of the United States, black people continued to be enslaved, the last four million black slaves were only liberated after the Civil War in 1865. Due to notions of white supremacy, they were treated as second-class citizens; the Naturalization Act of 1790 limited U. S. citizenship to whites only, only white men of property could vote. These circumstances were changed by Reconstruction, development of the black community, participation in the great military conflicts of the United States, the elimination of racial segregation, the civil rights movement which sought political and social freedom. In 2008, Barack Obama became the first African American to be elected President of the United States; the first African slaves arrived via Santo Domingo to the San Miguel de Gualdape colony, founded by Spanish explorer Lucas Vázquez de Ayllón in 1526. The marriage between Luisa de Abrego, a free black domestic servant from Seville and Miguel Rodríguez, a white Segovian conquistador in 1565 in St. Augustine, is the first known and recorded Christian marriage anywhere in what is now the continental United States.
The ill-fated colony was immediately disrupted by a fight over leadership, during which the slaves revolted and fled the colony to seek refuge among local Native Americans. De Ayllón and many of the colonists died shortly afterwards of an epidemic and the colony was abandoned; the settlers and the slaves who had not escaped returned to Haiti, whence. The first recorded Africans in British North America were "20 and odd negroes" who came to Jamestown, Virginia via Cape Comfort in August 1619 as indentured servants; as English settlers died from harsh conditions and more Africans were brought to work as laborers. An indentured servant would work for several years without wages; the status of indentured servants in early Virginia and Maryland was similar to slavery. Servants could be bought, sold, or leased and they could be physically beaten for disobedience or running away. Unlike slaves, they were freed after their term of service expired or was bought out, their children did not inherit their status, on their release from contract they received "a year's provision of corn, double apparel, tools necessary", a small cash payment called "freedom dues".
Africans could raise crops and cattle to purchase their freedom. They raised families, married other Africans and sometimes intermarried with Native Americans or English settlers. By the 1640s and 1650s, several African families owned farms around Jamestown and some became wealthy by colonial standards and purchased indentured servants of their own. In 1640, the Virginia General Court recorded the earliest documentation of lifetime slavery when they sentenced John Punch, a Negro, to lifetime servitude under his master Hugh Gwyn for running away. In the Spanish Florida some Spanish married or had unions with Pensacola, Creek or African women, both slave and free, their descendants created a mixed-race population of mestizos and mulattos; the Spanish encouraged slaves from the southern British colonies to come to Florida as a refuge, promising freedom in exchange for conversion to Catholicism. King Charles II of Spain issued a royal proclamation freeing all slaves who fled to Spanish Florida and accepted conversion and baptism.
Most went to the area around St. Augustine, but escaped slaves reached Pensacola. St. Augustine had mustered an all-black militia unit defending Spain as early as 1683. One of the Dutch African arrivals, Anthony Johnson, would own one of the first black "slaves", John Casor, resulting from the court ruling of a civil case; the popular conception of a race-based slave system did not develop until the 18th century. The Dutch West India Company introduced slavery in 1625 with the importation of eleven black slaves into New Amsterdam. All the colony's slaves, were freed upon its surrender to the British. Massachusetts was the first British colony to recognize slavery in 1641. In 1662, Virginia passed a law that children of enslaved women took the status of the mother, rather than that of the father, as under English common law; this principle was called partus sequitur ventrum. By an act of 1699, the colony ordered all free blacks deported defining as slaves all people of African descent who remained in the c
