Yearly Change: For 2019: absolute change in total population (increase or decrease in number of people) over the last year (from Jto June 30 2019). For all other years: latest year annual percentage change equivalent assuming homogeneous change in the preceding five year period, calculated through reverse compounding. Yearly % Change: For 2019: percentage change in total population over the last year (from Jto June 30 2019). World Population Prospects: The 2019 Revision. Population: Overall total population (both sexes and all ages) in the country as of July 1 of the year indicated, as estimated by the United Nations, Department of Economic and Social Affairs, Population Division. Year: as of July 1 of the year indicated. This value can differ from the Yearly % Change shown in the historical table, which shows the last year equivalent percentage change assuming homogeneous change in the preceding five year period. The Yearly Population Growth Rate chart plots the annual percentage changes in population registered on July 1 of each year, from 1951 to 2019. The Population of the United States (1950 - 2019) chart plots the total population count as of July 1 of each year, from 1950 to 2019. The data is given as of 1st of January of an year.The United States Population (Live) counter shows a continuously updated estimate of the current population of the United States of America delivered by Worldometer's RTS algorithm, which processes data collected from the United Nations Population Division. This type of pyramid is common for developing countries with declining fertility rate but still high birth and death rates. The groups are the same as we used above: population under 15, between 15 and 64 and population which is over 65 year old.Īs we can see the World population pyramid has an expanding type. We prepared a simplified model of the population distribution pyramid which is broken down into 3 main age groups. percentage of population between 15 and 64 years old

Map and list of the world by density of population at Īs of the beginning of 2022 according to our estimates the world had the following population age distribution: 26.2 List of countries by surface area and density by United Nations Statistics Division Sum of land and water areas within international boundaries and coastlines of all the countries in the world. This includes all continental and island land area as well as Antarctica.

Since the Earth's total area is about 510 million square kilometers, the world population density can be calculated in several ways: This is the sum of land and water areas within international boundaries and coastlines of all the countries in the world. This number is calculated using 7,948,118,521 people as the world population and 136,120,354 km 2 (52,556,368 mi 2)as Earth's total area. The world population density is 58.4 people per square kilometer (151.2 per mi 2) as of September 2022. The biggest groups are: Christianity (32%) and Islam (24%). More than half of the world's population identify with a religious group. And in 2023 India is expected to become the most populous country in the world. Despite the fact that China is curently the most populous country in the world, India's population growths much faster. About 36 % of the World population live just in these two countries. There are just 2 countries in the world with a population more than 1 billion people: China and India. More than 70% of the world population live in 20 most populous countries of the world. The median age of the world's population is estimated to be 31 years in 2020 (30.3 and 31.8 for male and female accordingly) It means that we have slightly more men then women. World population is expected to reach 8 billion people in 2023 according to our estimates.Ĭurrently, the world population is increasing by more than 90 million per year. The first billion was reached around 1800 and in just 200 years we reached 7 billion.Īccording to Population Division of United Nations Department of Economic and Social Affairs, these are the main milestones: World population - is the total number of humans currently living in the World.Īs of today, the total population of the world is around 8.02 billion people.
