Although the founding fathers declared American independence in 1776, and the subsequent Revolutionary War ended in 1783, individual states did not officially join the union until 1787. The first states to ratify the U.S. Constitution were Delaware, Pennsylvania and New Jersey, in December 1787, and they were joined by the remainder of the thirteen ex-British colonies by 1790. Another three states joined before the turn of the nineteenth century, and there were 45 states by 1900. The final states, Alaska and Hawaii, were admitted to the union in 1959, almost 172 years after the first colonies became federal states. Secession in the American Civil War The issues of slavery and territorial expansion in the mid nineteenth century eventually led to the American Civil War, which lasted from 1861 until 1865. As the U.S. expanded westwards, a moral and economic argument developed about the legality of slavery in these new states; northern states were generally opposed to the expansion of slavery, whereas the southern states (who were economically dependent on slavery) saw this lack of extension as a stepping stone towards nationwide abolition. In 1861, eleven southern states seceded from the Union, and formed the Confederate States of America. When President Lincoln refused to relinquish federal property in the south, the Confederacy attacked, setting in motion the American Civil War. After four years, the Union emerged victorious, and the Confederate States of America was disbanded, and each individual state was readmitted to Congress gradually, between 1866 and 1870. Expansion of other territories Along with the fifty U.S. states, there is one federal district (Washington D.C., the capital city), and fourteen overseas territories, five of which with a resident population (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the U.S. Virgin Islands). In 2019, President Trump inquired about the U.S. purchasing the territory of Greenland from Denmark, and, although Denmark's response indicated that this would be unlikely, this does suggest that the US may be open to further expansion of it's states and territories in the future. There is also a movement to make Washington D.C. the 51st state to be admitted to the union, as citizens of the nation's capital (over 700,000 people) do not have voting representation in the houses of Congress nor control over many local affairs; as of 2020, the U.S. public appears to be divided on the issue, and politicians are split along party lines, as D.C. votes overwhelmingly for the Democratic nominee in presidential elections.

In the past four centuries, the population of the United States has grown from a recorded 350 people around the Jamestown colony of Virginia in 1610, to an estimated 331 million people in 2020. The pre-colonization populations of the indigenous peoples of the Americas have proven difficult for historians to estimate, as their numbers decreased rapidly following the introduction of European diseases (namely smallpox, plague and influenza). Native Americans were also omitted from most censuses conducted before the twentieth century, therefore the actual population of what we now know as the United States would have been much higher than the official census data from before 1800, but it is unclear by how much. Population growth in the colonies throughout the eighteenth century has primarily been attributed to migration from the British Isles and the Transatlantic slave trade; however it is also difficult to assert the ethnic-makeup of the population in these years as accurate migration records were not kept until after the 1820s, at which point the importation of slaves had also been illegalized. Nineteenth century In the year 1800, it is estimated that the population across the present-day United States was around six million people, with the population in the 16 admitted states numbering at 5.3 million. Migration to the United States began to happen on a large scale in the mid-nineteenth century, with the first major waves coming from Ireland, Britain and Germany. In some aspects, this wave of mass migration balanced out the demographic impacts of the American Civil War, which was the deadliest war in U.S. history with approximately 620 thousand fatalities between 1861 and 1865. The civil war also resulted in the emancipation of around four million slaves across the south; many of whose ancestors would take part in the Great Northern Migration in the early 1900s, which saw around six million black Americans migrate away from the south in one of the largest demographic shifts in U.S. history. By the end of the nineteenth century, improvements in transport technology and increasing economic opportunities saw migration to the United States increase further, particularly from southern and Eastern Europe, and in the first decade of the 1900s the number of migrants to the U.S. exceeded one million people in some years. Twentieth and twenty-first century The U.S. population has grown steadily throughout the past 120 years, reaching one hundred million in the 1910s, two hundred million in the 1960s, and three hundred million in 2007. In the past century, the U.S. established itself as a global superpower, with the world's largest economy (by nominal GDP) and most powerful military. Involvement in foreign wars has resulted in over 620,000 further U.S. fatalities since the Civil War, and migration fell drastically during the World Wars and Great Depression; however the population continuously grew in these years as the total fertility rate remained above two births per woman, and life expectancy increased (except during the Spanish Flu pandemic of 1918).

Since the Second World War, Latin America has replaced Europe as the most common point of origin for migrants, with Hispanic populations growing rapidly across the south and border states. Because of this, the proportion of non-Hispanic whites, which has been the most dominant ethnicity in the U.S. since records began, has dropped more rapidly in recent decades. Ethnic minorities also have a much higher birth rate than non-Hispanic whites, further contributing to this decline, and the share of non-Hispanic whites is expected to fall below fifty percent of the U.S. population by the mid-2000s. In 2020, the United States has the third-largest population in the world (after China and India), and the population is expected to reach four hundred million in the 2050s.

In the aftermath of the First World War, the League of Nations was established at the Paris Peace Conference of June 28, 1919, and the Covenant of the League of Nations made up Part I of the Treaty of Versailles. The League came into being on January 10, 1920, with the primary objective of preventing further global conflicts by maintaining international peace and security through diplomacy and negotiation rather than military action, as well as a focus on the protection of human rights and international disarmament. Unfortunately for the League, the U.S. Congress refused to join (despite President Wilson being the leading architect behind the League's founding), while the other Great Powers (Britain, France, Italy, and Japan) were reluctant to provide military assistance or adhere to economic sanctions put in place by the League. By the end of 1934, League membership reached its highest level of 58 member states; however, this was the year after the two primary aggressors of the Second World War, Germany and Japan, had left the League. Over the next decade, the rise of fascism and the impact of the Second World War saw the inevitable collapse of the League of Nations, and its official dissolution in 1946. Development of the United Nations The League of Nations was replaced by the United Nations (UN) following the Second World War. The UN came into being in June 1945, when 50* governments met in San Francisco to draft the original UN Charter, which came into effect on October 24, 1945. Since its founding, there have been approximately 200 different member states of the United Nations, with some (such as Yugoslavia or East Germany) no longer existing, while others have been renamed or their borders have been redefined. The largest increases in membership came in the 1950s as many European colonies (mostly in Africa and Asia) gained independence, and again in the early 1990s, with the fall of the Soviet Union and communism in Eastern Europe. The latest member state to join the UN was South Sudan in 2011. International relations in the UN's early history were strained, as tensions caused by the Cold War impeded the UN's ability to act effectively, but since the Soviet Union's dissolution in 1991 the UN was able to expand and diversify its peacekeeping efforts with fewer obstacles. The six principal organizations of the UN are the General Assembly, the Security Council, the Economic and Social Council, the Trusteeship Council, the International Court of Justice and the UN Secretariat. The highest-ranking official in the UN is Secretary General António Guterres (former Prime Minister of Portugal). The UN is headquartered in New York, and has three regional headquarters in Geneva, Nairobi, and Vienna (and the International Court of Justice is based in The Hague, Netherlands). Non-member states of the UN Along with the 193 member states of the UN, there are two countries or territories with permanent observer status. The first of these is the Holy See (Vatican City), which is the only fully independent country in the world that is not a member state. However, it has full access to the UN's resources, but abstains from the voting process due to the Pope's preference not to get involved in geopolitical affairs. Palestine is the other state with this status, as the UN favors Palestine becoming a fully independent nation, but will not acknowledge this claim until Palestine's conflict with the UN member state Israel has been peacefully resolved. Since the 2023 Israeli invasion of Gaza, calls for Palestinian membership have grown, particularly from within the UN and its many organizations that have played an integral role in Gaza's daily operations since the 1950s. Of the other six states without non-member observer status, Kosovo's independence from Serbia has the most international support, and it is currently recognized by over 100 member states. The Republic of China (Taiwan) held China's seat in the UN from it's founding until 1971, where it was then transferred to the People's Republic of China (China). Since then, Taiwan has been represented at the UN by the Chinese government (who is one of the five permanent members of the UN Security Council), and only 13 member states recognize Taiwan's independence. As of 2025, Indonesia remains the only country to have ever withdrawn its UN membership, in 1965, although this was reinstated the following year.

Additional information on the aging population in the United States

High birth rates during the so-called baby boom years that followed World War II followed by lower fertility and morality rates have left the United States with a serious challenge in the 21st Century. However, the issue of an aging population is certainly not an issue unique to the United States. The age distribution of the global population shows that other parts of the world face a similar issue.

Within the United States, the uneven distribution of populations aged 65 years and over among states offers both major challenges and potential solutions. On the one hand, federal action over the issue may be contentious as other states are set to harbor the costs of elderly care in states such as California and Florida. That said, domestic migration from comparably younger states may help to fill gaps in the workforce left by retirees in others.

Nonetheless, aging population issues are set to gain further prominence in the political and economic decisions made by policymakers regardless of the eventual distribution of America’s elderly. Analysis of the financial concerns of Americans by age shows many young people still decades from retirement hold strong concern over their eventual financial position.

Preparation of this data collection was funded by grant

90-A-1279 from the United States Department of Health and Human

Services, Administration on Aging. Estimates of the population of persons 60 years old and older were received from the Census Bureau in printed form and were made machine-readable by staff at ICPSR. Other variables contained in this dataset were merged from existing machine-readable census files. The data concerning racial composition of counties were taken from the CENSUS OF POPULATION AND HOUSING, 1980 [UNITED STATES]: P.L. 94-171 POPULATION COUNTS (ICPSR 7854). The figures concerning per capita income were taken from the Bureau of the Census, GENERAL REVENUE SHARING, 1978 POPULATION ESTIMATES (ICPSR 7840). Variables include Federal Information Processing Standard (FIPS) state and county codes, 1978 per capita income of county, and total population of county broken down by sex, race, and age (in four-year increments with a category for persons 75 years old and older).
