According to our estimations, daily change rates of United States of America (USA) population in 2021 will be the following:
As of 1 January 2021, the population of United States of America (USA) was estimated to be 332,524,270 people. This is an increase of 0.75 % (2,485,194 people) compared to population of 330,039,076 the year before. In 2020 the natural increase was positive, as the number of births exceeded the number of deaths by 1,438,970. Due to external migration, the population increased by 1,046,224. The sex ratio of the total population was 0.975 (975 males per 1,000 females) which is lower than global sex ratio. The global sex ratio in the world was approximately 1,016 males to 1,000 females as of 2020.
Below are the key figures for United States of America (USA) population in 2020:
United States of America (USA) population density is 34.5 people per square kilometer (89.4/mi2) as of February 2021. Density of population is calculated as permanently settled population of United States of America (USA) divided by total area of the country. Total area is the sum of land and water areas within international boundaries and coastlines of United States of America (USA). The total area of United States of America (USA) is 9,632,030 km2 (3,718,948 mi2) according to the United Nations Statistics Division .
|Religion||Number of followers||Percentage of
|Religiously Unaffiliated||54,595,858||16.4 %|
|Folk or traditional religions||665,803||0.2 %|
As of the beginning of 2021 according to our estimates United States of America (USA) had the following population age distribution:
|- percentage of population under 15|
|- percentage of population between 15 and 64 years old|
|- percentage of population 65+|
In absolute figures (estimate):
We prepared a simplified model of the population distribution pyramid which is broken down into 3 main age groups. The groups are the same as we used above: population under 15, between 15 and 64 and population which is over 65 year old.
Note: The pyramid provided is not corresponding to data given above because the age groups have different number of years.
As we can see the United States of America (USA) population pyramid has a stationary type. Countries with such type of pyramid usually have declining birth rate and relatively low death rate. Which is more common for developed countries.
Dependency ratio of population is a ratio of people who are generally not in the labor force (the dependents) to workforce of a country (the productive part of population). The dependent part includes the population under 15 years old and people aged 65 and over. The productive part of population accordingly consists of population between 15 and 64 years.
This ratio shows the pressure on productive population produced by the dependent part of population.
The total dependency ratio of population in United States of America (USA) is 49.7 %.
The value of 49.7 % is relatively low. It shows that the dependent part of population is less than a half of the working part. In other words the working population (labor force) in United States of America (USA) must provide goods for itself and cover expenditure on children and aged persons. And this part of population is less than 50% of working population. The value of less than 50% means that the pressure on productive population in United States of America (USA) is relatively low.
Child dependency ratio is a ratio of people below working age (under 15) to workforce of a country.
Child dependency ratio in United States of America (USA) is 30.1 %.
Aged dependency ratio is a ratio of people above working age (65+) to workforce of a country.
Aged dependency ratio in United States of America (USA) is 19.7 %.
Life expectancy at birth is one of the most important demographic indicator. It shows the number of years a newborn infant would live assuming that birth and death rates will remain at the same level during the whole lifetime.
Total life expectancy (both sexes) at birth for United States of America (USA) is 78.4 years.
This is above the average life expectancy at birth of the global population which is about 71 years (according to Population Division of the Department of Economic and Social Affairs of the United Nations).
Male life expectancy at birth is 75.9 years.
Female life expectancy at birth is 80.9 years.
According to our estimates 263,102,447 persons or 99% of adult population (aged 15 years and above) in United States of America (USA) are able to read and write. Accordingly about 2,657,600 adults are illiterate.
Literacy rate for adult male population is 99% (128,384,329 persons). 1,296,811 are illiterate.
Literacy rate for adult female population is 99% (134,718,118 persons). 1,360,789 are illiterate.
Youth literacy rates are 99% and 99% for males and females accordingly. The overall youth literacy rate is 99%. Youth literacy rate definition covers the population between the ages of 15 to 24 years.
