why do they say population replacement level is 2.1 children/woman instead 2?
What is the reason for adding extra .1?

Because not every child will grow to adulthood, and not every adult will be able to procreate. The extra tenth allows for the casualties along the way.

Because those 2.1 children will, on average, be 1.1 boy and 1 girl. The population replacement level is one girl per woman.
It is not because 0.1 may die before adulthood - if half of the girls grow up and get 4 children each while the other half die early, we still say the reproduction rate is 2.
So childhood death has already been taken into account when the figures are presented.

It's a percentage of the population.

It is an average.
