As the United States has grown in area and population, new states have been formed out of U.S. territories or the division of existing states. The population figures provided here reflect modern state boundaries. Shaded areas of the tables indicate census years when a territory or the part of another state had not yet been admitted as a new state.
Nevada had the highest percentage growth in population from 2017 to 2018. At the 2020 census, 6.0% of the state's population were reported as under 5, 22.5% were under 18, and 16.1% were 65 or older. Females made up about 49.8% of the population. 19.1% of the population was reported as foreign-born.
The number shown is the average annual growth rate for the period. Population is based on the de facto definition of population, which counts all residents regardless of legal status or citizenship—except for refugees not permanently settled in the country of asylum, who are generally considered part of the population of the country of origin ...
Many cities in Nevada, Arizona and Texas topped the list for the highest population growth between 2017 and 2022, but Paradise bucks that trend. The latest population count was 183,321, down from ...
Graph of world population over the past 12,000 years . As a general rule, the confidence of estimates on historical world population decreases for the more distant past. Robust population data exist only for the last two or three centuries. Until the late 18th century, few governments had ever performed an accurate census.
[clarification needed] The birth rate (along with mortality and migration rates) is used to calculate population growth. The estimated average population may be taken as the mid-year population. [2] [3] When the crude death rate is subtracted from the crude birth rate (CBR), the result is the rate of natural increase (RNI). [4]
The doubling time (t d) of a population is the time required for the population to grow to twice its size. [24] We can calculate the doubling time of a geometric population using the equation: N t = λ t N 0 by exploiting our knowledge of the fact that the population (N) is twice its size (2N) after the doubling time. [20]
Globally, the rate of population growth has declined from a peak of 2.2% per year in 1963. [11] Population growth alongside increased consumption is a driver of environmental concerns, such as biodiversity loss and climate change, [12] [13] due to overexploitation of natural resources for human development.
