Let X be 1.

1-Child Policy may be weird (no offense), but I want to discuss about it. They have it in China. Well, I don't think there should be a one-child policy. If that's the case, well, their fertility rate is 1.58, and since it's below 2.10 (Normal Rate), why have it anyway? Here are some of the pros and cons (advantages and disadvantages):

Pros: Will lessen population growth

Cons: What if the president is a second child, third child, etc?

Now, let X be 2.

Not much weird, but it has been planned in the Philippines! Well, at least it's okay to implement it (our fertility rate is 3.1), just 1 above the normal rate. But, what's more weird (no offense) is what Hong Kong has! Imagine a fertility rate of 1.04, should there be even one?

Conclusion: State your opinions about 1 or 2 child policy.

Hi;

I would say they should stop population growth completely. 0 children, in about 100 years everything will be fine.

Okay, make it 110 years just to be extra safe.

Or work on improving other things which will enable us to support the population growth.

Now that is truly impossible.

Why not just ban any fancy cars, place high taxes on rich persons etc?

That will never be possible.

Hmm, I think I have to manipulate my population census. It's crazy to get so much by 2100! (My census reached 11-15 billion there ) So, I will change the lower by year rate to 1.5% from 1%. I'll try.

The future population. Look at the topic named "Future Population (End of the World in 3136?)"

But you did not describe your method. Did you just guess?

Hmm, I'll describe it. It's in Google Drive, but it's not the whole. I'll upload the files.

Hi mathaholic;

But how about your method?

I've an idea for estimating the population.

1. Develop a highly stinking apple juice.

2. Package it in packets which has your email on it.

3. Use aircrafts from the US Defense to drop these packets everywhere around.

4. The number of complain emails you get is the population of the eartg.

I'm not crazy, my mother had me tested.

I would say it would be less than the population of the earth.

Alternate method: do not package the appld juice just spill it.

You could also go around and ask everyone what their favorite color is...

The two child policy is the best for the children.

I think 1.79 children per family is best.
