How many people use the site plus?

i don't quite know exact amounts, but the amount of people that use alone is over 100 million people, so to estimate; i would have to say about 25% of those people use plus. meaning that it is about 25 million hope this kinda answered your question!

d. stage 4

explanation:

the existence of some kind of demographic transition is widely accepted in the social sciences because of the well-established historical correlation linking dropping fertility to social and economic development.[1] scholars debate whether industrialization and higher incomes lead to lower population, or whether lower populations lead to industrialization and higher incomes. scholars also debate to what extent various proposed and sometimes inter-related factors such as higher per capita income,lower mortality, old-age security, and rise of demand for human capital are involved.[2]

show options, then i will gladly answer you question.

have a good day.
