U.S. and World Population Clock

Here they can see very clearly how the population of the United States of America and additionally in the whole world is currently developing and how the population in the USA is composed.

 

The U.S. Population Clock

The U.S. population clock is based on a series of short-term projections for the resident population of the United States. This includes people whose usual residence is in the 50 states and the District of Columbia. These projections do not include members of the Armed Forces overseas, their dependents, or other U.S. citizens residing outside the United States.

The projections are based on a monthly series of population estimates starting with the April 1, 2020 resident population from the 2020 Census.

At the end of each year, a revised series of population estimates from the census date forward is used to update the short-term projections for the population clock. Once the updated series of monthly projections is completed, the daily population clock values are derived by interpolation. Within each calendar month, the daily numerical population change is assumed to be constant, subject to negligible differences caused by rounding.

Population estimates produced by the U.S. Census Bureau for the United States, states, metropolitan and micropolitan statistical areas, counties, cities, towns, as well as for Puerto Rico and its municipios can be found on the Population Estimates web page. Projections of the future population for the United States can be found on the Population Projections web page.

County Population by Age, Sex, Race, and Hispanic Origin

The United States Census Bureau provides annual population estimates by age, sex, race, and Hispanic origin for every county in the country. These estimates are based on a variety of data sources, such as birth and death records, administrative records, surveys, and census data. Estimates help understand demographic trends and characteristics of the county's population over time.

World Population is growing by over 200,000 people a day

The population of the world today is about 215,000 people larger than yesterday. The world population clock shows you in real time how fast it’s actually going. The development will put enormous pressure on Earth’s resources and we’ll need to find more sustainable ways of living. And fast!

Accelerating population growth

Around 1804, the world population reached 1 billion people. In 1927, the 2 billion mark was made. And then, the world population really took off. In the following 84 years, the world population grew by 5 billion people reaching 7 billion in 2011. And the growth continues. By 2023, world population reaches 8 billion people. Around 2037 it could hit 9 billion and by 2056 a massive 10 billion people.

An expanding world economy

For all of recorded history, a growing population has been accompanied by economic growth - and usually per capita growth as well. When the world population doubled in the 46 years between 1971 and 2017, the world economy more than quadrupled from $19.9 to $80.1 trillion (in constant prices). In about the same period from 1970 and 2010, human consumption of Earth's natural resources tripled.

The Population Pyramid

The age pyramid of the United States of America is a graphical representation of the distribution of its population by age and sex. It shows how the population is divided into different age groups, from the youngest (0-4 years) to the oldest (85 years and over), and how these groups vary by gender. The age pyramid can reveal important demographic trends and patterns, such as fertility, mortality, migration and aging.

One of the most noticeable features of the US age pyramid is the bulge of the baby boomers, the generation born between 1946 and 1964, who are now in their 50s and 60s. This cohort has a significant impact on the social and economic aspects of the country, as they enter retirement age and demand more health care and social services. Another prominent feature is the echo boomers or millennials, the children of the baby boomers, who are now in their 15s and 30s. This group is larger than their parents' generation, and represents a potential source of labor force and economic growth.

The US age pyramid also shows some gender differences, especially at older ages. Women tend to live longer than men, and therefore outnumber them in the oldest age groups. This creates a gender imbalance that affects various aspects of society, such as family structure, caregiving, income and poverty.

The shape of the US age pyramid is expected to change over time, as a result of changes in fertility, mortality and migration rates. According to projections by the US Census Bureau, the population will become older and more diverse in the coming decades. The baby boomers will continue to age and decline in size, while the millennials will become the largest generation in history. The proportion of people aged 65 and over will increase from 16% in 2020 to 23% in 2060, while the proportion of people under 18 will decrease from 22% to 19%. The population will also become more racially and ethnically diverse, as minorities will account for more than half of the population by 2045.

The future: A much bigger world economy

In 2000, the UN estimated that the global economy will grow between 10 and a massive 26 times during the 21st century. According to a report from PwC from 2017, the world economy is expected to double between 2016 and 2050 reaching over $150 trillion. Whatever the exact level of economic growth will be, such a massive economic growth will put enormous pressure on Earth’s resources. And we are already overusing at 175 percent…

World Population - History and Projection (1820-2100)

For the first time in modern history, the world's population is expected to almost stop growing by the end of this century, largely due to a falling global birth rate, according to a new analysis of United Nations data set by the United Nations. Performed by Pew Research. Center.

This video shows the World Population growth between the years 1820 and 2100, using historical and projected data. It uses a bar chart race for the countries (top 20) and a line chart shows continent's population evolution. Historical and projected population is based on the present countries.

By 2100, the world's population is expected to reach about 10.9 billion, with an annual growth rate of less than 0.1% - a sharp drop from the current rate. Since 1950, the world population has increased by 1-2% per year, the number of people has increased from 2.5 billion people to more than 7.7 billion people.

Ecological Footprint of the human population

The human population is dependent on the Earth's ecosystems to survive. But the relationship between man and nature has been thrown out of balance - quite a lot actually. Humanity now exceeds ecosystems’ capacity to support our way of life by 75 percent. Such a situation cannot go on. The world population is basically “taking a loan in nature” - a loan that future generations will have to repay.

Of course, It is not simply the number of people that determines the impact of the planet. It is how much we consume and how much waste we produce.

Historical Apportionment Data Map

This interactive tool allows them to view more than 10 decades of apportionment and population data.

Population change and population density data based on the number of residents in each census every ten years, including all people living in the United States at the time of each census. Population change is the rate at which the population changes between census decades.

Population density is a measure of the average number of people per square mile of land. Density ratings from 1 to 52 include the District of Columbia and Puerto Rico.

Distribution is the process of allocating representatives (or seats) in the United States House of Representatives among 50 states based on census population numbers every ten years. District of Columbia and Puerto Rico are not included. The population distribution in each state does not always coincide with the number of residents. For more information, see Historical Perspectives.

The population per representative is calculated by dividing the population proportionally by the number of representatives.

The "US" value for "Change Seats" indicates the total number of seats that were reallocated (i.e. moved from state to state) during that decade, except for the value 1910, which indicates the number of seats has been added to the United States House of Representatives since 1900 Alaska and Hawaii were recognized as states in 1959. Arizona and New Mexico were recognized as states in 1912. For distributions, data prior to these time periods are not displayed on the map.

In 1920, distribution calculations were submitted to Congress, but Congress did not redistribute that decade.
