So looking at birth rates, and the ONS quotes a required birth rate of 2.075 per woman to maintain a flat population.

I would have thought 2.0 would be the rate.

Anyone understand why they quote 2.075?

(This ignores migration, relates solely to the "natural" growth)

This new lockdown poll - what you reckon?

On a quick glance, I couldn't see an explanation but I would have thought that the 0.075 is there to cover things like infant mortality, car accidents etc.

Interestingly, the 2.075 figure is an average, but given some women will not have children, this means that those that do would need to have on average more than that number to maintain the population, and that just ain't going to happen.
