Global Population To Hit 9.9 Billion – PRB

Global population will reach 9.9 billion by 2050, up 2.3 billion or 29 percent from an estimated 7.6 billion people currently, according to projections by Population Reference Bureau (PRB) included in the 2018 World Population Data Sheet.

PRB continue to produce the World Population Data Sheet ( package annually since 1962.

The digital and print editions are widely used and cited by educators, policymakers, journalists, programme implementers, and others who value the Data Sheet as a trusted reference and source of timely demographic analysis, according to the data released to the Ghana News Agency.

This year’s edition provides the latest data on 26 key population, health, and environment indicators for the world, the world’s regions, and more than 200 countries and territories. Among the population projections included in the 2018 Data Sheet:

According to the Bureau, the population of 26 countries, including Ghana, nearly all in Africa, will at least double. The population of Niger, in West Africa is expected to nearly triple.

A total of 38 countries will have smaller populations in 2050 than in 2018. China will register the largest numerical population decrease about 50 million followed by Japan at 25 million and Russia at 9.4 million. Romania will see the largest percentage decline in population (23 percent).

The population of the United States will reach 390 million, up from 328 million in 2018.

China’s population will decrease by about 50 million from its current size to 1.34 billion. India will supplant China as the world’s most populous country with 1.68 billion people.

Nigeria will become the third most populous country as its population rises to 411 million, up 109 percent from 2018. Nigeria is currently the seventh most populous country.

Indonesia will record a population of 320 million.

The data said Chad, Democratic Republic of Congo and Somalia will have the highest total fertility rate at 6.4, 6.3 and 6.3 while the lowest total fertility rates in Singapore 1.2, Bosnia-Herzegovina 1.3 and Moldova will see downsizing rates.

For the 2018 ‘Changing Age Structures’ Data Sheet, PRB demographers analysed the changing age structures around the world, which can have important implications for countries’ economic and social trajectories, as well as their resource allocation and policy decisions.

As part of the analyses for this Data Sheet, PRB demographers grouped countries into five age dependency categories to better illustrate their demographic challenges and opportunities.

The categories integrated two factors: the child dependency ratio—the ratio of children (those under age 15) to the working-age population (ages 15 to 64); and the old-age dependency ratio-the ratio of older adults (ages 65 and older) to the working-age population.

Many countries in the world are experiencing—and will continue to experience—population aging, with steady increases in the number of older adults, both in absolute terms and as a percentage of the total population.

This trend poses challenges for countries in balancing the pension, health, and other benefits that older adults typically receive with investments in the well-being of younger generations.
