Much more.. . . The report also confirmed that the world’s population is growing older due to increasing life expectancy and falling fertility levels, and that the number of countries experiencing a reduction in population size is growing. The resulting changes in the size, composition and distribution of the world’s population have important consequences for achieving the Sustainable Development Goals (SDGs), the globally agreed targets for improving economic prosperity and social well-being while protecting the environment.
The new population projections indicate that nine countries will make up more than half the projected growth of the global population between now and 2050: India, Nigeria, Pakistan, the Democratic Republic of the Congo, Ethiopia, the United Republic of Tanzania, Indonesia, Egypt and the United States of America (in descending order of the expected increase). Around 2027, India is projected to overtake China as the world’s most populous country.
The population of sub-Saharan Africa is projected to double by 2050 (99% increase). Regions that may experience lower rates of population growth between 2019 and 2050 include Oceania excluding Australia/New Zealand (56%), Northern Africa and Western Asia (46%), Australia/New Zealand (28%), Central and Southern Asia (25%), Latin America and the Caribbean (18%), Eastern and South-Eastern Asia (3%), and Europe and Northern America (2%).
The global fertility rate, which fell from 3.2 births per woman in 1990 to 2.5 in 2019, is projected to decline further to 2.2 in 2050. In 2019, fertility remains above 2.1 births per woman, on average, over a lifetime in sub-Saharan Africa (4.6), Oceania excluding Australia/New Zealand (3.4), Northern Africa and Western Asia (2.9), and Central and Southern Asia (2.4). (A fertility level of 2.1 births per woman is needed to ensure replacement of generations and avoid population decline over the long run in the absence of immigration). . . .
