1890 United States Census
The Eleventh United States Census was taken beginning June 2, 1890. It determined the resident population of the United States to be 62,979,766—an increase of 25.5 percent over the 50,189,209 persons enumerated during the 1880 census. The data was tabulated by machine for the first time; the data reported that the distribution of the population had resulted in the disappearance of the American frontier. Most of the 1890 census materials were destroyed in a 1921 fire and fragments of the US census population schedule exist only for the states of Alabama, Illinois, New Jersey, New York, North Carolina, South Dakota, Texas, the District of Columbia; this was the first census in which a majority of states recorded populations of over one million, as well as the first in which multiple cities – New York as of 1880, Philadelphia – recorded populations of over one million. The census saw Chicago rank as the nation's second-most populous city, a position it would hold until 1990, in which Los Angeles would supplant it.
The 1890 census collected the following information: The 1890 census was the first to be compiled using methods invented by Herman Hollerith and was overseen by Superintendents Robert P. Porter and Carroll D. Wright. Data was entered on a machine readable medium, punched cards, tabulated by machine; the net effect of the many changes from the 1880 census: the larger population, the number of data items to be collected, the Census Bureau headcount, the volume of scheduled publications, the use of Hollerith's electromechanical tabulators, was to reduce the time required to process the census from eight years for the 1880 census to six years for the 1890 census. The total population of 62,947,714, the family, or rough, was announced after only six weeks of processing; the public reaction to this tabulation was disbelief, as it was believed that the "right answer" was at least 75,000,000. The United States census of 1890 showed a total of 248,253 Native Americans living in the United States, down from 400,764 Native Americans identified in the census of 1850.
The 1890 census announced that the frontier region of the United States no longer existed, that the Census Bureau would no longer track the westward migration of the U. S. population. Up to and including the 1880 census, the country had a frontier of settlement. By 1890, isolated bodies of settlement had broken into the unsettled area to the extent that there was hardly a frontier line; this prompted Frederick Jackson Turner to develop his Frontier Thesis. The original data for the 1890 Census is no longer available. All the population schedules were damaged in a fire in the basement of the Commerce Building in Washington, D. C. in 1921. Some 25 % of the materials were presumed another 50 % damaged by smoke and water; the damage to the records led to an outcry for a permanent National Archives. In December 1932, following standard federal record-keeping procedures, the Chief Clerk of the Bureau of the Census sent the Librarian of Congress a list of papers to be destroyed, including the original 1890 census schedules.
The Librarian was asked by the Bureau to identify any records which should be retained for historical purposes, but the Librarian did not accept the census records. Congress authorized destruction of that list of records on February 21, 1933, the surviving original 1890 census records were destroyed by government order by 1934 or 1935; the other censuses for which some information has been lost are the 1810 enumerations. Few sets of microdata from the 1890 census survive, but aggregate data for small areas, together with compatible cartographic boundary files, can be downloaded from the National Historical Geographic Information System.

Chicago the City of Chicago, is the most populous city in Illinois, as well as the third most populous city in the United States. With an estimated population of 2,716,450, it is the most populous city in the Midwest. Chicago is the principal city of the Chicago metropolitan area referred to as Chicagoland, the county seat of Cook County, the second most populous county in the United States; the metropolitan area, at nearly 10 million people, is the third-largest in the United States, the fourth largest in North America and the third largest metropolitan area in the world by land area. Located on the shores of freshwater Lake Michigan, Chicago was incorporated as a city in 1837 near a portage between the Great Lakes and the Mississippi River watershed and grew in the mid-nineteenth century. After the Great Chicago Fire of 1871, which destroyed several square miles and left more than 100,000 homeless, the city made a concerted effort to rebuild; the construction boom accelerated population growth throughout the following decades, by 1900 Chicago was the fifth largest city in the world.
Chicago made noted contributions to urban planning and zoning standards, including new construction styles, the development of the City Beautiful Movement, the steel-framed skyscraper. Chicago is an international hub for finance, commerce, technology, telecommunications, transportation, it is the site of the creation of the first standardized futures contracts at the Chicago Board of Trade, which today is the largest and most diverse derivatives market gobally, generating 20% of all volume in commodities and financial futures. O'Hare International Airport is the one of the busiest airports in the world, the region has the largest number of U. S. highways and greatest amount of railroad freight. In 2012, Chicago was listed as an alpha global city by the Globalization and World Cities Research Network, it ranked seventh in the entire world in the 2017 Global Cities Index; the Chicago area has one of the highest gross domestic products in the world, generating $680 billion in 2017. In addition, the city has one of the world's most diversified and balanced economies, not being dependent on any one industry, with no single industry employing more than 14% of the workforce.
Chicago's 58 million domestic and international visitors in 2018, made it the second most visited city in the nation, behind New York City's approximate 65 million visitors. The city ranked first place in the 2018 Time Out City Life Index, a global quality of life survey of 15,000 people in 32 cities. Landmarks in the city include Millennium Park, Navy Pier, the Magnificent Mile, the Art Institute of Chicago, Museum Campus, the Willis Tower, Grant Park, the Museum of Science and Industry, Lincoln Park Zoo. Chicago's culture includes the visual arts, film, comedy and music jazz, soul, hip-hop and electronic dance music including house music. Of the area's many colleges and universities, the University of Chicago, Northwestern University, the University of Illinois at Chicago are classified as "highest research" doctoral universities. Chicago has professional sports teams in each of the major professional leagues, including two Major League Baseball teams; the name "Chicago" is derived from a French rendering of the indigenous Miami-Illinois word shikaakwa for a wild relative of the onion, known to botanists as Allium tricoccum and known more as ramps.
The first known reference to the site of the current city of Chicago as "Checagou" was by Robert de LaSalle around 1679 in a memoir. Henri Joutel, in his journal of 1688, noted that the eponymous wild "garlic" grew abundantly in the area. According to his diary of late September 1687:...when we arrived at the said place called "Chicagou" which, according to what we were able to learn of it, has taken this name because of the quantity of garlic which grows in the forests in this region. The city has had several nicknames throughout its history such as the Windy City, Chi-Town, Second City, the City of the Big Shoulders, which refers to the city's numerous skyscrapers and high-rises. In the mid-18th century, the area was inhabited by a Native American tribe known as the Potawatomi, who had taken the place of the Miami and Sauk and Fox peoples; the first known non-indigenous permanent settler in Chicago was Jean Baptiste Point du Sable. Du Sable arrived in the 1780s, he is known as the "Founder of Chicago".
In 1795, following the Northwest Indian War, an area, to be part of Chicago was turned over to the United States for a military post by native tribes in accordance with the Treaty of Greenville. In 1803, the United States Army built Fort Dearborn, destroyed in 1812 in the Battle of Fort Dearborn and rebuilt; the Ottawa and Potawatomi tribes had ceded additional land to the United States in the 1816 Treaty of St. Louis; the Potawatomi were forcibly removed from their land after the Treaty of Chicago in 1833. On August 12, 1833, the Town of Chicago was organized with a population of about 200. Within seven years it grew to more than 4,000 people. On June 15, 1835, the first public land sales began with Edmund Dick Taylor as U. S. Receiver of Public Monies; the City of Chicago was incorporated on Saturday, March 4, 1837, for several decades was the world's fastest-growing city. As the site of the Chicago Portage, the city became an important transportation hub between the eastern and western United States.

North American Numbering Plan
The North American Numbering Plan is a telephone numbering plan that encompasses twenty-five distinct regions in twenty countries in North America, including the Caribbean. Some North American countries, most notably Mexico, do not participate in the NANP; the NANP was devised in the 1940s by AT&T for the Bell System and independent telephone operators in North America to unify the diverse local numbering plans, established in the preceding decades. AT&T continued to administer the numbering plan until the breakup of the Bell System, when administration was delegated to the North American Numbering Plan Administration, a service, procured from the private sector by the Federal Communications Commission in the United States; each participating country forms a regulatory authority that has plenary control over local numbering resources. The FCC serves as the U. S. regulator. Canadian numbering decisions are made by the Canadian Numbering Administration Consortium; the NANP divides the territories of its members into numbering plan areas which are encoded numerically with a three-digit telephone number prefix called the area code.
Each telephone is assigned a seven-digit telephone number unique only within its respective plan area. The telephone number consists of a four-digit station number; the combination of an area code and the telephone number serves as a destination routing address in the public switched telephone network. For international call routing, the NANP has been assigned the international calling code 1 by the International Telecommunications Union; the North American Numbering Plan conforms with ITU Recommendation E.164, which establishes an international numbering framework. From its beginnings in 1876 and throughout the first part of the 20th century, the Bell System grew from local or regional telephone systems; these systems expanded by growing their subscriber bases, as well as increasing their service areas by implementing additional local exchanges that were interconnected with tie trunks. It was the responsibility of each local administration to design telephone numbering plans that accommodated the local requirements and growth.
As a result, the Bell System as a whole developed into an unorganized system of many differing local numbering systems. The diversity impeded the efficient operation and interconnection of exchanges into a nationwide system for long-distance telephone communication. By the 1940s, the Bell System set out to unify the various numbering plans in existence and developed the North American Numbering Plan as a unified, systematic approach to efficient long-distance service that did not require the involvement of switchboard operators; the new numbering plan was accepted in October 1947, dividing most of North America into eighty-six numbering plan areas. Each NPA was assigned a numbering plan area code abbreviated as area code; these codes were first used by long-distance operators to establish long-distance calls between toll offices. The first customer-dialed direct call using area codes was made on November 10, 1951, from Englewood, New Jersey, to Alameda, California. Direct distance dialing was subsequently introduced across the country.
By the early 1960s, most areas of the Bell System had been converted and DDD had become commonplace in cities and most larger towns. In the following decades, the system expanded to include all of the United States and its territories, Canada and seventeen nations of the Caribbean. By 1967, 129 area codes had been assigned. At the request of the British Colonial Office, the numbering plan was first expanded to Bermuda and the British West Indies because of their historic telecommunications administration through Canada as parts of the British Empire and their continued associations with Canada during the years of the telegraph and the All Red Line system. Not all North American countries participate in the NANP. Exceptions include Mexico, Saint Pierre and Miquelon, the Central American countries and some Caribbean countries; the only Spanish-speaking state in the system is the Dominican Republic. Mexican participation was planned, but implementation stopped after three area codes had been assigned, Mexico opted for an international numbering format, using country code 52.
The area codes in use were subsequently withdrawn in 1991. Area code 905 for Mexico City, was reassigned to a split of area code 416 in the Greater Toronto Area. Dutch-speaking Sint Maarten joined the NANP in September 2011, receiving area code 721; the NANP is administered by the North American Numbering Plan Administration. Today, this function is overseen by the Federal Communications Commission, which assumed the responsibility upon the breakup of the Bell System; the FCC solicits private sector contracts for the role of the administrator. The service was provided by a division of Lockheed Martin. In 1997, the contract was awarded to Neustar Inc.. In 2012, the contract was renewed until 2017. In 2015, the contract beginning 2017 was granted to Ericsson; the vision and goal of the architects of the North American Numbering Plan was a system by which telephone subscribers in the United States and Canada could themselves dial and establish a telephone call to any other subscriber wi
Westmont is a village in DuPage County, United States. Westmont is a community of 5.03 square miles in area. Westmont had a 2000 population of 24,554, a partial special census was conducted 2007 resulting in a population of 26,211, the census of 2010 put the population at 24,685, it is located 18 miles west of the Chicago Loop in the southeastern portion of DuPage County. The area known as Westmont was inhabited by the Potawatami until the year 1833. After several failed attempts by the U. S. government to persuade the Native Americans to move from the area, in 1833, the Native Americans agreed under coercion to vacate their land for nominal payment. The development of the Illinois-Michigan Canal, authorized by the State of Illinois in the 1820s but delayed in construction until the 1830s, contributed to Westmont's early growth; when the economic Panic of 1837 halted canal construction, many of the workers turned to farming, agriculture became the major occupation, with produce sold in nearby Chicago.
The area around Westmont became one of the most prosperous sections of the state. In order to transport agricultural products into the city of Chicago, construction of a plank road originating in Chicago began in 1840; the plank road was placed over the nine-mile swamp separating Chicago and the area that became Westmont, reached Naperville, Illinois by 1851. Today, this roadway is known as Ogden Avenue; the plank road soon became inadequate. The railroad line was approved, with the first train in 1864. "Greg’s Station," from which Westmont developed, was a stop to load agricultural and dairy products. The town transitioned from an agricultural community to a commuter community, with the early growth and development centered around the railroad station. In the early 1900s, plats for the Village of Westmont were laid out and roads were dedicated. Westmont was incorporated on November 4, 1921; the Village did not encourage concentrated commercial or industrial growth until the 1950s, with the development of some light service companies, industrial firms, wholesaling firms.
However, it was not until the 1970s the Westmont began to grow in earnest. New subdivisions and multiple family housing units led to the tripling of the population. Robbie Russo, hockey player from Westmont who plays for the Arizona Coyotes Kira Salak and journalist Ty Warner and inventor of Beanie Babies Muddy Waters, considered the father of Chicago blues, it is bounded on the north by the Village of Oak Brook, on the east by the Village of Clarendon Hills, on the south by the City of Darien and on the west by the Village of Downers Grove. It is nearly wholly within Downers Grove Township. According to the 2010 census, Westmont has a total area of 5.136 square miles, of which 5.03 square miles is land and 0.106 square miles is water. As of the special census of 2007, there were 26,211 people, 9,900 households, 5,979 families residing in the village; the population density was 5,014.4 people per square mile. There were 10,269 housing units at an average density of 2,097.1 per square mile. The racial makeup of the village was 78.02% White, 5.38% African American, 0.13% Native American, 11.95% Asian, 2.41% from other races, 2.11% from two or more races.
Hispanic or Latino people of any race comprised 6.98% of the population. There were 9,900 households. 47.1% were married couples living together, 10.4% had a female householder with no husband present, 39.6% were non-families. 32.5% of all households were made up of individuals and 11.8% had someone living alone, 65 years of age or older. The average household size was 2.37 and the average family size was 3.05. The population was spread out with 21.9% under the age of 18, 8.3% from 18 to 24, 33.8% from 25 to 44, 20.3% from 45 to 64, 15.7% who were 65 years of age or older. The median age was 36 years. For every 100 females, there were 87.4 males. For every 100 females age 18 and over, there were 82.9 males. The median income for a household in the village was $51,422, the median income for a family was $64,472. Males had a median income of $42,909 versus $33,690 for females; the per capita income for the village was $26,394. About 3.8% of families and 5.8% of the population were below the poverty line, including 4.8% of those under age 18 and 8.5% of those age 65 or over.
Westmont has a Westmont Metra station on Metra's BNSF Railway Line, which provides daily rail service between Aurora and Chicago, Illinois. U. S. Route 34, Interstate 88 located north of the Village, Interstate 55 to the South, Interstate 294 to the East and Interstate 355 to the West, provide access to the rest of the Chicago Region.

Per capita income
Per capita income or average income measures the average income earned per person in a given area in a specified year. It is calculated by dividing the area's total income by its total population. Per capita income is national income divided by population size. Per capita income is used to measure an area's average income and compare the wealth of different populations. Per capita income is used to measure a country's standard of living, it is expressed in terms of a used international currency such as the euro or United States dollar, is useful because it is known, is calculable from available gross domestic product and population estimates, produces a useful statistic for comparison of wealth between sovereign territories. This helps to ascertain a country's development status, it is one of the three measures for calculating the Human Development Index of a country. In the United States, it is defined by the U. S. Census Bureau as the following: "Per capita income is the mean money income received in the past 12 months computed for every man and child in a geographic area."
Critics claim that per capita income has several weaknesses in measuring prosperity: Comparisons of per capita income over time need to consider inflation. Without adjusting for inflation, figures tend to overstate the effects of economic growth. International comparisons can be distorted by cost of living differences not reflected in exchange rates. Where the objective is to compare living standards between countries, adjusting for differences in purchasing power parity will more reflect what people are able to buy with their money, it does not reflect income distribution. If a country's income distribution is skewed, a small wealthy class can increase per capita income while the majority of the population has no change in income. In this respect, median income is more useful when measuring of prosperity than per capita income, as it is less influenced by outliers. Non-monetary activity, such as barter or services provided within the family, is not counted; the importance of these services varies among economies.
Per capita income does not consider whether income is invested in factors to improve the area's development, such as health, education, or infrastructure.

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
A ZIP Code is a postal code used by the United States Postal Service in a system it introduced in 1963. The term ZIP is an acronym for Zone Improvement Plan; the basic format consists of five digits. An extended ZIP+4 code was introduced in 1983 which includes the five digits of the ZIP Code, followed by a hyphen and four additional digits that reference a more specific location; the term ZIP Code was registered as a servicemark by the U. S. Postal Service, but its registration has since expired; the early history and context of postal codes began with postal district/zone numbers. The United States Post Office Department implemented postal zones for numerous large cities in 1943. For example: The "16" was the number of the postal zone in the specific city. By the early 1960s, a more organized system was needed, non-mandatory five-digit ZIP Codes were introduced nationwide on July 1, 1963; the USPOD issued its Publication 59: Abbreviations for Use with ZIP Code on October 1, 1963, with the list of two-letter state abbreviations which are written with both letters capitalized.
An earlier list in June had proposed capitalized abbreviations ranging from two to five letters. According to Publication 59, the two-letter standard was "based on a maximum 23-position line, because this has been found to be the most universally acceptable line capacity basis for major addressing systems", which would be exceeded by a long city name combined with a multi-letter state abbreviation, such as "Sacramento, Calif." along with the ZIP Code. The abbreviations have remained unchanged, with the exception of Nebraska, changed from NB to NE in 1969 at the request of the Canadian postal administration, to avoid confusion with the Canadian province of New Brunswick. Robert Moon is considered the father of the ZIP Code; the post office only credits Moon with the first three digits of the ZIP Code, which describe the sectional center facility or "sec center." An SCF is a central mail processing facility with those three digits. The fourth and fifth digits, which give a more precise locale within the SCF, were proposed by Henry Bentley Hahn Sr.
The SCF sorts mail to all post offices with those first three digits in their ZIP Codes. The mail is sorted according to the final two digits of the ZIP Code and sent to the corresponding post offices in the early morning. Sectional centers do not deliver mail and are not open to the public, most of their employees work the night shift. Mail picked up at post offices is sent to their own SCF in the afternoon, where the mail is sorted overnight. In the case of large cities, the last two digits coincide with the older postal zone number thus: In 1967, these became mandatory for second- and third-class bulk mailers, the system was soon adopted generally; the United States Post Office used a cartoon character, which it called Mr. ZIP, to promote the use of the ZIP Code, he was depicted with a legend such as "USE ZIP CODE" in the selvage of panes of postage stamps or on the covers of booklet panes of stamps. In 1971 Elmira Star-Gazette reporter Dick Baumbach found out the White House was not using a ZIP Code on its envelopes.
Herb Klein, special assistant to President Nixon, responded by saying the next printing of envelopes would include the ZIP Code. In 1983, the U. S. Postal Service introduced an expanded ZIP Code system that it called ZIP+4 called "plus-four codes", "add-on codes", or "add-ons". A ZIP+4 Code uses the basic five-digit code plus four additional digits to identify a geographic segment within the five-digit delivery area, such as a city block, a group of apartments, an individual high-volume receiver of mail, a post office box, or any other unit that could use an extra identifier to aid in efficient mail sorting and delivery. However, initial attempts to promote universal use of the new format met with public resistance and today the plus-four code is not required. In general, mail is read by a multiline optical character reader that instantly determines the correct ZIP+4 Code from the address—along with the more specific delivery point—and sprays an Intelligent Mail barcode on the face of the mail piece that corresponds to 11 digits—nine for the ZIP+4 Code and two for the delivery point.
For Post Office Boxes, the general rule is. The add-on code is one of the following: the last four digits of the box number, zero plus the last three digits of the box number, or, if the box number consists of fewer than four digits, enough zeros are attached to the front of the box number to produce a four-digit number. However, there is no uniform rule, so the ZIP+4 Code must be looked up individually for each box; the ZIP Code is translated into an Intelligent Mail barcode, printed on the mailpiece to make it easier for automated machines to sort. A barcode can be printed by the sender, it is better to let the post office put one on. In general, the post office uses OCR technology, though in some cases a human might have to read and enter the address. Customers who send bulk mail can get a discount on postage if they have printed the barcode themselves and have presorted the mai
