Clara: Has birth control and family planning led to the slowing down of growth rate and became the social norm today?
Do you think reasons like birth control, natural disaster, family planning, laws, kids being too expensive and infertility has led to the slowing down of the growth rate so that it has become the modern economic and social norm today?

I mean there’s a faster than predicted decline in birth rate across the world, a lot of improvements in family planning and basic education across the world and even China’s one child policy.

But then again

Statistics are LIES
Census are probably inaccurate.

So has it become a modern economic and social norm to have less children these days?

The birth rate has declined for most cultures, some continue to have higher rates. What we are actually witnessing is a cultural change across the Planet. Family planning and birth control have led to the decline of cultures. Large families are not the norm in developed countries and many people have no children at all.

Nearly all world growth to 2050 is projected to occur in developing regions, that is, in Africa, Asia, and Latin America. The population of the industrial (or more developed) world is expected to remain close to its current size, and, in some countries, population is likely to decline. Thus the distribution of world population will shift significantly. Over the next 50 years, the share of world population in Sub-Saharan Africa, in particular, will rise from 10 to 17 percent of the world total, while the share in Europe will decline from 13 to 7 percent. The population in industrial regions as a whole, now outnumbered almost 4 to 1 by the population in developing countries, will be outnumbered by about 7 to 1 by the year 2050.
