U.S. Demographic History

The Demographic history of the U.S. covers population growth, geographical distribution by states and urban-rural, internal migration, and components of change (births, deaths, immigration), as well as race and ethnicity, and population policy.

Summary of conditions in 2007

The American population has grown steadily to 300 million in 2006 from the 3.9 million were counted in the first census of 1790. However, the annual percentage rate of growth in has shown a nearly continuous decline. The growth has resulted primarily from “natural increase” (more births than deaths) but immigration has played an increasingly important role in recent decades with the origins of immigrants having shifted from Europe to Mexico, Central America, and Asia in recent decades. The most rapid population growth in the United States in recent decades has been in the West and South with slower growth occurring in the Northeast and Midwest. Five western and southern states-California, Florida, Texas, Arizona and Nevada--were the major centers of growth since the 1970s.

The population of the United States is aging, though not as fast as Western Europe and Japan. The median age in the United States was nearly 36 in 2003 compared to about 23 in 1900 and is projected to be more than 40 by 2050. More male than female babies are born, but because of lower mortality rates among females, they come to outnumber males between the ages of 20 to 30 and by the elderly ages the number of females is nearly double that of the number of males. The population is becoming increasingly racially and ethnically diverse. Growth among Hispanic, Asian and black is substantially greater than among whites or Anglos. By 2002 there were at least 37.4 million Hispanics (plus several million uncounted illegal immigrants). As a result, ethnic minorities made up about xx percent of the total population in 2005. Minority populations have a much lower level of access to socioeconomic resources, such as education and savings,s and smaller resource bases than majority groups.

Families are changing rapidly. The proportion of married-couple households is declining relative to nontraditional household forms, with heated debates underway about the legal status of same-sex marriages. With the decrease in married-couple households, the high rate of divorce (about 50%), and higher ages at first marriage, the size of households has declined substantially with one- and two-person households now accounting for a majority of all households.

Jobs are changing as well. Farming has shrunk to under 1%, while the rust belt had mile after mile of closed factories. With rapidly rising educational levels, the new jobs are opening in technical fields. The shortage of highly trained engineers has attracted hundreds of thousands of well educated engineers and scientists from around the world. Less skilled jobs are plentiful in areas such as restaurants and construction, where less educated immigrants congregate. Although wages are stagnant for blue collar workers, a steady increase in incomes and wealth holding on the part of the upper middle class, augmented by sky-high incomes for celebrities and CEOs, has increased the level of income inequality.

Marriage and fertility

In Plymouth Plantation in the 17th century, a fairly comprehensive demographic study was done by historian John Demos for his 1970 work A Little Commonwealth. He reports that the size of the average household size grew as time passed in Plymouth colony, with the average of 7.8 children per family for first-generation families, 8.6 children for second-generation families, and 9.3 for third-generation families. Child mortality also decreased over this time, with 7.2 children born to first-generation families living until their 21st birthday. The number increased to 7.9 children by the third generation.

Mortality

In Plymouth Plantation in the 17th century, life expectancy was higher for men than for women. Of the men who survived until the age of 21, the average life expediency was 69.2 years. Over 55 percent of these men lived past 70, less than 15 percent died before the age of 50. For women, the numbers are much lower, owing to the difficulties inherent in childbirth. The average life expediency of women at the age of 21 was only 62.4 years. Of these women, less than 45 percent lived past 70, and about 30 percent died before the age of 50.

Population projections

The US population in 1900 was 76 million. In 1950, it rose to 152 million by 2000 it had reached 282 million. By 2050, 420 million and then 571 million by 2100.

Urban - Rural Distributions

Internal Migration

Rural flight is the departure of excess populations (usually young men and women) from farm areas. In some cases whole familes left, as in the Dust Bowl in the 1930s. Much of rural America has seen steady population decline since 1920.

Black Migration out of South

see Great Migration (African American) The Great Migration was the movement of millions African Americans out of the rural Southern United States from 1914 to 1960. Most moved to large industrial cities, as well as to many smaller industrial cities. African-Americans moved as individuals or small groups. There was no government assistance. They migrated because of a variety of push and pull factors:

Push factors

1. Many African-Americans wanted to avoid the racial segregation of the Jim Crow South and sought refuge in the supposed "Promised Land" of the North where there was thought to be less segregation
2. The boll weevil infestation of the cotton fields of the South in the late 1910s, reduced the demand for sharecroppers.
3. The Great Mississippi Flood of 1927 and its aftermath displaced hundreds of thousands of African-American farm workers;

Pull factors

1. Income levels were much higher in the North, with far higher wages in the service sector.
2. The enormous growth of war industries in WW1 and WW2 created new job openings for blacks—not in the factories but in the service jobs that new factory workers vacated;
3. World War I effectively put a halt to the flow of European immigrants to the emerging industrial centers Northeast and Midwest, causing shortages of workers in the factories.
4. In the 1930s WPA, CCC and other relief programs in the North were more receptive to blacks. The WPA paid more in the North.
5. After 1940, as the U.S. rearmed for World War II (see Homefront-United States-World War II), industrial production in the Northeast, Midwest and West increased rapidly.
6. The FEPC equal opportunity laws were more enforced in the North and West.

Immigration

Colonial Era

Nearly all commercial activity was run in small privately owned businesses with good credit both at home and in England being essential since they were often cash poor. Most settlements were nearly independent of trade with Britain as most grew or made nearly everything they needed--the average cost of imports per most households was only about 5-15 English pounds per year. Most settlements were done by complete family groups with several generations often present in each settlement. Probably close to 80% of the families owned the land they lived and farmed on. They nearly all used English Common Law as their basic code of law and except initially for the Dutch, Swedes and Germans, spoke some dialect of English. They nearly all established their own popularly elected governments and courts on as many levels as they could and were nearly all, within a few years, mostly armed, self governing, self supporting and self replicating. This self ruling pattern became so ingrained that almost all new settlements by one or more groups of settlers would have their own government up and running shortly after they settled down for the next 200 years. Nearly all, after a hundred years plus of living together, had learned to tolerate other religions than their own. This was a major improvement from the often very bloody Reformation and Counter-Reformation wars going on in Europe in this period. British troops up until the French and Indian War in the 1760s were a great rarity in the colonies as the colonists provided nearly all their own law enforcement and militia forces they wanted or needed from their own ranks. The American Revolution was in many ways a fight to maintain the property and independence they already enjoyed as the British tried, belatedly, to exploit them for the benefit of the crown and Parliament. Nearly all colonies and later, states in the United States, were settled by migration from another colony or state, as foreign immigration usually only played a minor role after the initial settlements were started. Many new immigrants did end up on the frontiers as that was where the land was usually the cheapest.

New England

The New England colonists were the most urban and educated of all the colonists and had many skilled farmers as well as tradesmen and skilled craftsmen among them. They mostly settled in small villages for mutual support (nearly all had their own militias) and common religious activity. Shipbuilding, commerce, agriculture and fisheries were their main income sources. New England's healthy climate (the cold winters killed the mosquitoes and other disease-bearing insects), small wide-spread villages (minimizing spread of disease) and abundant food supply resulted in the lowest death rate and highest birth rate (marriage was expected and birth control was not, and a much higher than average number of children and mothers survived) of any place in the world. The eastern and northern frontier around the initial New England settlements was mainly settled by the Yankee descendants of the original New Englanders. Emigration to the New England colonies after 1640 and the start of the English Civil War decreased to less than 1% (about equal to the death rate) in nearly all years prior to 1845. The rapid growth of the New England colonies (~700,000 by 1790) was almost entirely due to the high birth rate (>3%) and low death rate (<1%) per year.

Middle Colonies

The middle colonies' settlements were scattered west of New York City (est. 1626, taken over by the English in 1664) and Philadelphia, Pennsylvania (est. 1682). The Dutch-started colony of New York had the most eclectic collection of residents from many different nations and prospered as a major trading and commercial center after about 1700. The Pennsylvania colonial center was dominated by the Quakers for decades after they emigrated, mainly from the North Midlands of England, from about 1680 to 1725. The main commercial center of Philadelphia was run mostly by prosperous Quakers, supplemented by many small farming and trading communities with a strong German contingent located in several small towns in the Delaware River valley.

Many more settlers arrived in the middle colonies starting in about 1680 when Pennsylvania was founded and many Protestant sects were encouraged to settle there by freedom of religion and good land--cheap. They came by the was about 60% British and 33% of German extraction. By 1780 in New York about 17% of the population were descendants of Dutch settlers and the rest were mostly English with a wide mixture of other Europeans and about 6% Blacks. New Jersey and Delaware had a majority of British with 7-11% German-descended colonists, about 6% black population, and a small contingent of Swedish descendants of New Sweden. Nearly all were at least third-generation natives.

Frontier

The colonial western frontier was mainly settled from about 1717 to 1775 by mostly Presbyterian settlers from northern England border lands, Scotland, and Northern Ireland, fleeing bad times and persecution in those areas. After the American Revolution these same areas in Britain were the first to resume significant immigration. Most initially landed in family groups in Philadelphia or Baltimore but soon migrated to the western frontier where land was cheaper and restrictions less onerous.

Natural Growth

All the colonies, after they were started, grow almost entirely by natural growth with foreign born populations rarely exceeding 10% (except in isolated instances). The last significant colonies to be settled mainly by immigrants were Pennsylvania in the early 1700s, Georgia and the Borderlands in the late 1700s as migration (not immigration) continued to provide nearly all the settlers for each new colony or state. This pattern would continue throughout U.S. History. The extent of colonial settlements by 1800 is shown by this map from the [great] University of Texas map collection. [1]

1. Maine was part of Massachusetts from about 1652 to 1820, when it was granted statehood.
2. New Hampshire was part of Massachusetts until about 1685, when it was split off and established under a British appointed governor. It was one of the original 13 colonies.
3. Vermont was contested between the French and British settlers until the French and Indian war (1758-1765) drove out the French authorities. The territory was then disputed between Massachusetts, New York and New Hampshire until the settlers declared their independence from all of them and were accepted as the 14th state in 1791 and participated in the 1790 census a year late.
4. Plymouth, Massachusetts despite being the first permanent New England settlement, lost its charter in 1690 and became part of the Massachusetts colony.
5. By 1784 all slavery in the New England states was either completely prohibited or transitioning to its total prohibition.
6. By 1804 all slavery in the Middle colonies (except Delaware [6.6% Black]) was either completely prohibited or was transitioning to its total prohibition.
7. All slavery was prohibited in the entire U.S. in 1865 by the 13th amendment to the constitution.

Population growth is nearly always by natural increase but significant immigration can sometimes be seen in some states when populations grow by more than 80% {a 3% growth rate) in a 20 year interval.

Population in 1790

According to the source, The Source: A Guidebook of American Genealogy by Kory L. Meyerink and Loretto Dennis Szucs, the following were the countries of origin for new arrivals coming to the United States before 1790. The regions marked * were part of Great Britain. The ancestry of the 3.9 million population in 1790 has been estimated by various sources by sampling last names in the 1790 census and assigning them a country of origin. The Irish in the 1790 census were mostly Scots Irish. The French were mostly Huguenots. The total U.S. Catholic population in 1790 was probably less than 5%. The Indian population inside territorial U.S. 1790 boundaries was less than 100,000.

3. Germany in this time period consists of a large number of separate countries, the largest of which was Prussia.
4. Jewish settlers were from several European countries.
5. The Other category probably contains mostly English ancestry settlers; but the loss of several states detailed census records in the burning of Washington D.C. in the War of 1812 makes estimating closer difficult. Nearly all states that lost their 1790 (and 1800) census records have tried to reconstitute their original census from tax records etc. with various degrees of success. The summaries of the 1790 and 1800 census from all states survived.
6. The Total is the total immigration over the approximately 130 year span of colonial existence of the U.S. colonies as found in the 1790 census. Many of the colonists, especially from the New England colonies, are already into their fifth generation of being in America. At the time of the American Revolution the foreign born population is estimated to be from 300,000 to 400,000.

The 1790 population already reflects the approximate 50,000 “Loyalists or Tories”, who emigrated to Canada at the end of the American Revolution and the less than 10,000 more who emigrated to other British possessions including England.

Already by 1790 the ancestry question is starting to become meaningless as many people from many different countries intermarry in each generation and nearly all these ancestries are starting to merge to become American. The total white population in 1790 was about 80% British ancestry and roughly doubles by natural increase every 25 years. The native born population of the U.S. has never fallen below 85% of the population after about 1675--100 years before the American Revolution.

Relentless population expansion pushed the U.S. frontier to the Pacific by 1848. Given the U.S. geography, most immigrants came long distances to settle in the U.S.. However the Irish leaving Canada for the US in the 1840s, the French Canadians who came down from Quebec after 1860, and the Mexicans who came north after 1911, found it easy to move back and forth.

Immigration 1790 to 1849

In the early years of the U.S., immigration was only about 6000 people a year on average, including French refugees from the slave revolt in Haiti. The French Revolution, starting in 1789, and the Napoleonic Wars from 1792 to 1814 severely limited immigration from Europe. The War of 1812 (1812-1814) with Britain again prevented any significant immigration. By 1808, Congress had banned the importation of slaves, slowing that human traffic to a trickle. After 1820, immigration gradually increased. For the first time, federal records, including ship passenger lists, were kept for immigration. Total immigration for one year in 1820 was 8,385, gradually building to 23,322 by 1830 with 143,000 total immigrating during the intervening decade. From 1831 to 1840, immigration increased greatly, to 599,000 total, as 207,000 Irish, even before the famine of 1845-49, started to emigrate in large numbers as Britain eased travel restrictions. 152,000 Germans, 76,000 British, and 46,000 French formed the next largest immigrant groups in that decade. From 1841 to 1850, immigration exploded to 1,713,000 total immigrants as at least 781,000 Irish, with the famine of 1845-1919 driving them, fled their homeland to escape poverty and death. The British, attempting to divert some of this traffic to help settle Canada, offered bargain fares of 15 shillings, instead of the normal 5 pounds (100 shillings) for transit to Canada. Thousands of poor Irish took advantage of this offer, and headed to Canada on what came to be called the "coffin ships" because of their high death rates. Once in Canada, many Irish walked across the border or caught an intercoastal freighter to the nearest major city in the United States - usually Boston or New York. Bad potato crops and failed revolutions struck the heart of Europe in 1848, contributing to the decade's total of 435,000 Germans, 267,000 British and 77,000 French immigrants. Bad times in Europe drove people out; land, relatives, freedom, opportunity and jobs in America lured them in.

Population and Foreign Born 1790 to 1849 Census Population, Immigrants per Decade
Census	Population	Immigrants-1	Foreign Born	%
1790	3,918,000	60,000
1800	5,236,000	60,000
1810	7,036,000	60,000

1850	23,054,000	1,713,000	2,244,000	9.7%

The number of immigrants from 1830 on are from immigration records. The census of 1850 was the first census in which place of birth was asked. It is probably a reasonable estimate that the foreign born population in the U.S. reached its minimum in about 1815 at something like 100,000 or 1.4% of the population. By 1815, most of the immigrants that arrived before the American Revolution had passed on, and there had been almost no new immigration.

1. The total number immigrating in each decade from 1790 to 1820 are estimates.
2. The number foreign born in 1830 and 1840 decades are extrapolations.

Nearly all population growth up to 1830 was by internal increase; about 98.5% of the population was native-born. By 1850, this had shifted to about 90% native-born. The first large-scale Catholic immigration started in the mid 1840s from Germany and Ireland.

In 1848, following conquest of the Southwest in the Mexican war American citizenship to approximately 60,000 Mexican residents of the New Mexico Territory and 10,000 living in California. In 1849, the California Gold Rush spurred significant immigration from Mexico, South America, China, Australia, Europe and caused a mass migration within the US, resulting in California gaining statehood in 1850, with a population of about 90,000.

Easterlin Models

Richard Easterlin is an economist and professor of economics who has researched and published much literature on economic growth in the United States. In one of Richard Easterlin’s articles, published in 2000, titled, Twentieth Century American Population Growth, he explains the growth pattern of American population in the twentieth century by examining the fertility rate fluctuations and the decreasing mortality rate. In his article, Easterlin attempts to prove the cause of the Baby Boom and Baby Bust by the “relative income” theory, despite the various other theories that these events have been attributed to. The “relative income” theory suggests that couples choose to have children based on a couple’s ratio of potential earning power and the desire to obtain material objects. This ratio depends on the economic stability of country and how people are raised to value material objects. The “relative income” theory explains the Baby Boom by suggesting that the late 1940s and 1950s brought low desires to have material objects, because of the Great Depression and WWII, as well as huge job opportunities, because of being a post war period. These two factors gave rise to a high relative income, which encouraged high fertility. Following this period, the next generation had a greater desire for material objects, however, an economic slowdown in the United States, made jobs harder to acquire. This resulted in lower fertility rates causing the Baby Bust.

Regional trends

Between, 1880 and 1900, the urban population of the United States rose from 28% to 40% (1), and reached 50% by 1920, in part due to 9,000,000 European immigrants. After 1890, the US rural population began to plummet, as farmers were displaced by mechanization and forced to migrate to urban factory jobs. After World War II, the US experienced a shift away from the cities, mostly due to the gaining popularity of the automobile and heavy government funding of suburban housing and highways. Many of the original manufacturing cities lost as much as half their population between 1950 and 1980. There was a shift in the population from the dense manufacturing centers of the Northeast (rust belt) to the outer suburbs of these cities and to newer, less dense cities in the Southwest (sun belt).
