China has been adopting the one-child policy. Assume it stays always true.?

Question

How long does it takes for the population to go down to 500 million.
Assume
Current population -1500 million
birthrate-13.14 births / 1,000 population
Death rate:
6.94 deaths / 1,000 population
I not sure if I provide sufficient information.

Answer 1

I think that you need to research China's one child policy and do a report on it. It surely makes sense as the population is so large there now. This policy is more economically enforced and exists mainly in the large cities. Couples sometimes move to the countryside and have several children...there it is allowed.

Back to your problem: there are still more births than deaths so the population will increase ! 13.14-6.94 = 6.2 per 1000 population

Unless the problem has bad data the goal of 500 million will not be met.

Answer 2

i do no longer are attentive to it, the gender ratio in China isn't that drastic, by what human beings say it very just about seems there is purely a handful of ladies folk for a million.5 billion of adult males... it is punctiliously unrealistic. international locations around the globe have choppy gender ratios, and China's infrequently worse than them. From the government's place you will discover China is lots much less classic in terms of gender matters than earlier - the government banned any form of prediction on the gender of the toddler earlier delivery, those families who've a widespread-born female could have yet another baby, and of course twins and triplets and beautiful information. China actual has a miles better share of working women folk than the US, or for that depend maximum folk of the stronger international, the attractiveness of ladies folk into no longer purely commonplace artwork, yet in addition each and every expert pastime shows how far China has stronger considering its imperialist days. ok, positioned it into the scope of issues - Britain industrialised in 1800, and ladies folk purely carried out extra constructive social prestige after WWI, it extremely is a rattling century long of artwork. China industrialised in 1970, and ever considering then women folk are deemed in each and every way equals of adult males (i'm chinese language, who is conscious extra constructive than me?), it is infrequently a million/2 a century of efforts. And yet human beings are criticising the government for chinese language human beings's classic evaluations, evaluations that are at as quickly as dying out?

Answer 3

More people are being born than dying so the population would increase in this situation
