The graphs above show the very rapid growth of the world population. The is largely due to vast improvements in public health care and sanitation.

Fortunately economic improvements lead to reduced birth rates. The world population growth has been very rapid. It slows, though, as countries become more affluent - people marry later, space their kids, start having children later, and have fewer children. And affluence leads to better birth control. And retirement plans replace children to take care of parents when they get older.

It is true that the poorest areas continue to have the most children. Advanced economies like the USA, Europe, and Japan have much lower birth rates.  Most of the growth in the USA is from immigration.

Zero Population Growth in a nation or the world is when population growth rates become 2.1 children per mother. https://en.wikipedia.org/wiki/Zero_population_growth

Negative population growth results from a replacement rate lower than 2.1. Countries such as Japan and China have reached this rate. Much of Europe has also reached that rate.

World Population Projections

The world population is estimated to number 7.086 billion by the United States Census Bureau (USCB).

Current projections show a continued increase in population in the near future (but a steady decline in the population growth rate), with the global population expected to reach between 7.5 and 10.5 billion by 2050.^[2][9][10] Various longer-term estimates predict further growth, stagnation, or even overall decline in the global population by 2150.^[11] Some analysts have questioned the sustainability of further world population growth, citing the growing pressures on the environment, global food supplies, and energy resources.^[12][13][14]
