The size, composition and density of the US population.

in search of a better life and go settlers went to America.However, the density of the US population is still much lower than in other developed countries (with a few exceptions).

indigenous population - Indians

the current territory of the United States before the European colonization of the Indians settled.About 400 tribes of up to 2-3 million people were resettled throughout the American soil.

European colonies began to form in this area in the 16-17 centuries.The main British colonizers began: British, Irish, Scottish.However, from Europe to the Americas flocked and other nationalities: Swedes, Dutch, French and others.

indigenous population - Indians - almost undergone extermination.Those who did not die, were settled on a reservation.By the early 20th century the Indians declined to 200 thousand people.However, they too are part of the population of the USA.

active immigration

most mass movement of immigrants to America were in the middle of the 19th century.In Europe, at a specified t

ime it was very unstable environment both economically and socially.About four million people in the period came to the United States.They were mostly Irish and Germans.

in 17-18 centuries came to America as slaves from the African continent many blacks.By the mid-19th century, their number is already about 3.2 million people.

As a result, the assimilation of all races and nationalities of the US, the number of the population continued to increase.

During the War of Independence, the influx of immigrants slowed, but then resumed and continued to grow at an accelerated pace.It is estimated that from 1820 to 2000, came to America about seventy million people.

Barrier immigration

to stop the flow of overseas immigration to the United States began to issue special laws governing entry into the country.The first one was adopted in the 20s of the 20th century.Although he has limited the influx of migrants, but not so much.It reduces the number of immigrants from Europe and Asia, but increased the number of countries in the Americas.

In 1965, a new immigration law even tougher to restrict entry to the United States.For different groups of countries have been set strict quotas.The right of priority entrance used only by scientists, skilled workers are rare professions, relatives of US citizens.Now, on average annually in the United States attracts about 1 million persons.

the United States: the number of people

According to national census of 2010, the number of the US population was about 309 million people.Trehsotmillionny resident of this country was born in 2006.Annual population growth (natural and migration), more than three million people.

Today, the US population is 320 million. Pers.The population of this country is the third largest in the world after China and India, which have already exceeded the figure of 1 billion.By the way, the Russian Federation in this list is the place with the number 9, less is almost twice than in the States.

racial makeup of the US population of approximately characterized as follows: white - 78%, blacks - 13.1%, Asians - 5%, Indians, Aleuts and Eskimos - 1.2%.Among white Hispanics make up 16.7%.Among immigrants (Census Bureau data for 2006) Europeans, there were 169 197 million.The Slavs are presented mostly Ukrainians and Poles.

wide scope

US population density is far from the highest in the world (16,500 pers. / Sq. Km, Monaco).On the contrary, the country is one of the last places on this indicator among developed countries.Inferior to her only Austria and Canada.The density of the US population an average of 33.1 persons per square kilometer.

Of course, residents are not equally distributed across the country.This is due primarily to the history of the United States land development and favorable conditions for living.The colonization of America began in the north-east - on the Atlantic coast and in the lakeside region.Today it is the most populated areas of the United States.The density of population there is 100 people per 1, in some states (New Jersey, Rhode Island, Massachusetts, and others), this figure is even more - 250-350 people. /

As the distance from the coast population density decreases.Mountain states, such as Wyoming and Colorado, populated by small (2 to 12 persons per sq. Km).But least of all people, of course, Alaska - 0.3 persons / sq.


In the early 20th century, the United States could still be attributed to the predominantly rural country.But then in America began rapid urbanization.Now to the question of how people in the US, you can answer: predominantly urban.

Although the city and its suburbs occupy only about six percent of the country, that's where most of the population is concentrated - 74%.In this regard, particularly revealing is California, where the urban population is 91%.Not far behind and the Mid Atlantic States - more than 80%.Agriculture and less populated states are considered to be the Central Plains and the South.Although recent urbanization accelerating.

In the US, a lot of small towns, but the great mass of the urban population accounts for megacities.Ten US cities have a population of over a million people.The biggest of them - New York.Its population is nearly 8.5 million.Second and third places are taken by Los Angeles (about four million) and Chicago (about three million).Closes ten "millionaire" San Jose (1.2 million people).

agglomeration and mega US

highest density of the US population accounts for agglomeration and mega-cities.More than three hundred

agglomerations are formed in the United States.Each of them includes a central city with a population of not less than fifty thousand people and its suburbs.

largest agglomeration of the United States, it is also the second largest in the world - New York.It includes not only New York and its suburbs, but also seven cities.Its total area is about thirty-one thousand kilometers, and the population - about twenty-one million people.

continue to grow, the agglomeration began to form mega-cities.So, on the Atlantic coast of the United States has formed a large area (two hundred kilometers wide and a thousand - long) continuous development, combining a metropolitan area of ​​Washington, Baltimore, Philadelphia, New York and Boston.More than forty million people live in this Megalopolis, which is called as follows: Northeast megalopolis.

immaterial inferior in size and population are two major Northeast megalopolis megalopolis USA.It Chipitts and San San.In these three mega-cities account for half of the urban population States.

Other characteristics of the population

How many population in the United States, we already know.It remains to say that women in the US more than men.The average life expectancy at women - 81 years old, have a strong half of humanity - 75 years.

average birth rate declines.Currently, he is 14 children per 1,000 inhabitants.

The religious composition of the population is dominated by Christians.More than half - Protestants (51.3%), Catholics - 23.9%.Of course, there are also Jews, Muslims and Buddhists.

The official language is English US (it is somewhat different from the classical version).
