[TREND] (Technical Terms & Definitions Below)
The United States is the third-most populous country in the world, with an estimated population of 329,227,746 as of January 28, 2020. The United States Census Bureau shows a population increase of 0.75% for the twelve-month period ending in July 2012. Though high by industrialized country standards, this is below the world average annual rate of 1.1%. The total fertility rate in the United States estimated for 2019 is 1.71 children per woman, which is below the replacement fertility rate of approximately 2.1.
The U.S. population almost quadrupled during the 20th century—at a growth rate of about 1.3% a year—from about 76 million in 1900 to 281 million in 2000. It is estimated to have reached the 200 million mark in 1967, and the 300 million mark on October 17, 2006. Foreign-born immigration has caused the U.S. population to continue its rapid increase, with the foreign-born population doubling from almost 20 million in 1990 to over 45 million in 2015,[11] representing one-third of the population increase. Population growth is fastest among minorities as a whole, and according to the Census Bureau's estimation for 2012, 50.4% of U.S. children under the age of 1 belonged to ethnic minority groups.
White people constitute the majority of the U.S. population, with a total of about 234,370,202 or 73% of the population as of 2017. "Non-Hispanic Whites" make up 60.7% of the country's population, their share of the U.S. population is expected to fall below 50% by 2045, primarily due to immigration and low birth rates.
Hispanic and Latino Americans accounted for 48% of the national population growth of 2.9 million between July 1, 2005, and July 1, 2006. Immigrants and their U.S.-born descendants are expected to provide most of the U.S. population gains in the decades ahead.
The Census Bureau projects a U.S. population of 417 million in 2060, a 38% increase from 2007 (301.3 million), and the United Nations estimates that the U.S. will be among the nine countries responsible for half the world's population growth by 2050, with its population being 402 million by then (an increase of 32% from 2007). In an official census report, it was reported that 54.4% (2,150,926 out of 3,953,593) of births in 2010 were to "non-Hispanic whites". This represents an increase of 0.3% compared to the previous year, which was 54.1%.
[TECHNICAL TERMS & DEFINITIONS]
*AGE STRUCTURE (POPULATION PYRAMID)
The composition of a population as determined by the number or proportion of males and females in each age category. The age-sex structure of a population is the cumulative result of past trends in fertility, mortality, and migration.
**POPULATION GROWTH RATE
The number of people added to (or subtracted from) a population in a year due to natural increase and net migration expressed as a percentage of the population at the beginning of the time period.
***TOTAL FERTILITY RATE (TFR)
The average number of children that would be born alive to a woman (or group of women) during her lifetime if she were to pass through her childbearing years conforming to the age-specific fertility rates of a given year.
****POTENTIAL SUPPORT RATIO
A number of people age 15–64 per one older person aged 65 or older. This ratio describes the burden placed on the working population (unemployment and children are not considered in this measure) by the non-working elderly population.
*****RATE OF NATURAL INCREASE (RNI)
The rate of natural increase refers to the difference between the number of live births and the number of deaths occurring in a year, divided by the mid-year population of that year, multiplied by a factor (usually 1,000).
It is equal to the difference between the crude birth rate and the crude death rate. This measure of the population change excludes the effects of migration.
