The number, composition and density of the US population. How many people are there in the US?
In search of a better life, immigrants traveled to America. However, the density of the US population is still much lower than in other developed countries (with a few exceptions).
Indigenous people & ndash; Indians.
The territory of the present US before the European colonization was inhabited by Indians. About 400 tribes of up to 2-3 million people were settled throughout the American land.
European colonies began to form on this territory in 16-17 centuries. The main colonizers were the British: the British, the Irish, the Scots. However, representatives of other nationalities also rushed from Europe to the American continent: the Swedes, the Dutch, the French, and others.
Indigenous people & ndash; Indians & ndash; almost was exterminated. Those who did not die were placed on the reservation. By the beginning of the 20th century, the number of Indians was reduced to 200 thousand people. However, they are also part of the US population.
Active immigration.
The most massive movement of immigrants to America occurred in the mid-19th century. In Europe at that time, the situation was very unstable, both economically and socially. About four million people in this period arrived in the United States. Mostly they were Irish and Germans.
In the 17-18 centuries, many blacks came to America as slaves from the African continent. By the mid-19th century, their number was already around 3.2 million.
As a result, all races and nationalities of the United States were assimilated, the number of people continued to increase.
During the war for independence, the influx of immigrants stopped, but then resumed and continued to grow at an accelerated pace. It is estimated that from 1820 to 2000, about seventy million people came to America.
The barrier of immigration.
To stop the flow of overseas immigration, in the US began to issue special laws that regulate the entry into the country. The first of these was adopted in the 1920s. Although he limited the influx of immigrants, but not so significantly. The number of immigrants from Europe and Asia has decreased, but the number of immigrants from the countries of the American continent has increased.
In 1965, the new immigration law further restricted entry to the States. Strict quotas were established for different groups of countries. The priority right of entry was used only by scientists, skilled workers of rare occupations, relatives of American citizens. Now an average of about 1 million immigrants come to the United States annually.
US: the number of people.
According to the 2010 general census, the US population was about 309 million people. Three hundred millionth resident of this country was born in 2006. Annual population growth (natural and migratory) exceeds three million people.
Today, the US population is 320 million people. In terms of population, this country ranks third in the world after China and India, which have already crossed the figure of 1 billion. By the way, the Russian Federation in this list is ranked 9th with an amount that is almost two times less than in the United States.
The racial makeup of the US population is approximately characterized in this way: white & ndash; 78%, black & ndash; 13.1%, Asians & ndash; 5%, Indians, Aleuts and Eskimos & ndash; 1.2%. Among whites, 16.7% are Hispanic. Among the immigrants (data of the Census Bureau for 2006), Europeans numbered 169 197 million people. The Slavs are mostly represented by Ukrainians and Poles.
Wide open spaces.
The density of the US population is far from the highest in the world (16,500 people per square kilometer, Monaco). On the contrary, this country is one of the last places in this indicator among the developed countries of the world. Only Austria and Canada are inferior to it. The density of the US population on average is 33.1 people per square kilometer.
Of course, residents are not equally distributed throughout the country. This is due primarily to the history of US land development and favorable living conditions. The colonization of America began in the northeast & ndash; on the Atlantic coast and in the Lake Priozerne. Today, these are the most populated areas of the United States. The density of the population there reaches 100 people per 1 sq. Km. km, in some states (New Jersey, Rhode Island, Massachusetts and others) this figure is even greater & ndash; 250-350 people per square meter. km.
As the distance from the coast, population density decreases. Mountain states, for example, Wyoming and Colorado, are inhabited a little (from 2 to 12 people per sq. Km.). But least of all people, of course, in Alaska & ndash; 0.3 people per square meter. km.
Urbanization of the population.
In the early 20th century, the US could still be attributed to countries predominantly rural. But then in America began rapid urbanization. Now the question of what kind of population in the US, you can answer: mostly urban.
Although the cities and their suburbs occupy only about six percent of the country’s territory, that’s where most of the population is concentrated & ndash; 74%. In this regard, particularly indicative is California, where the urban population is 91%. Not too far behind and Mid-Atlantic states & ndash; more than 80%. Agrarian and less populated are the states of the Central Plains and the south of the country. Although the urbanization of the latter is gaining momentum.
In the US, many small towns, but a large mass of the urban population is in megacities. Ten US cities have a population of over one million people. The biggest of them is & ndash; New York. Its population is almost 8.5 million people. The second and third places are occupied by Los Angeles (about four million) and Chicago (about three million). Closes the top ten millionaire & raquo; San Jose (1 million 200 thousand people).
Agglomeration and megacities of the USA.
The largest density of the US population is in agglomeration and megacities.
More than three hundred agglomerations are formed in the United States of America. Each of them includes a central city with a population of at least fifty thousand people and its suburbs.
The largest agglomeration of the United States, it is the second largest in the world, & ndash; New York. It includes not only New York with its suburbs, but also seven other large cities. Its total area is about thirty-one thousand kilometers, and the population is & ndash; about twenty one million people.
Continuing to grow, agglomerations began to form megalopolises. So, on the Atlantic coast of the United States, a large area (two hundred kilometers wide and one thousand) long buildings was formed, combining the agglomerations of Washington, Baltimore, Philadelphia, New York and Boston. More than forty million people live in this megalopolis, which is called so: Bosvash.
In addition, the two largest megalopolises of the United States are inferior in size and in size to the population of Boswash. This is Chipitts and San San. In these three megalopolises, half the urban population of the United States resides.
Other characteristics of the population.
How many people in the US, we already know. It remains to be said that there are more women among Americans than men. Average life expectancy in the fair sex & ndash; 81 years old, in the strong half of humanity & ndash; 75 years.
The average annual fertility rate is decreasing. At present, it is 14 children per 1000 inhabitants.
The religious composition of the population is dominated by Christians. More than half & ndash; Protestants (51.3%), Catholics & ndash; 23.9%. Of course, there are Jews, Muslims, and Buddhists.
The official language of the United States is English (it is somewhat different from the classical version).
