Hello!

- Step 1: multiply per 50% since half of the population are women (the rest gest inmediately excluded)

- Step 2: multiply again per 2%, that is the % of a woman´s life in which she is pregnant:

- 2 pregnacies on average per lady

- 1.8 years pregnant/life expectancy of 80 years old = ~2%

Alternatively, you can follow the approach you mention and divide the total population into age groups, in order to determine how many babies are born in a given year, to later divide by the total women. However, it´s much longer.

Hope it helps!

Cheers,

Clara
