Of course they could start having more children which would be a natural reaction to preserve your race, culture and way of life. Or they could open the floodgate and allow millions of invaders to completely change thier country.

Of course they could start having more children which would be a natural reaction to preserve your race, culture and way of life.

Very few people have children for such reasons. People have children for their own personal reasons - in poorer countries, children are intended to help work for the family unit and more are born. As the poorer countries start becoming more prosperous, the birth rate falls as parents weigh the increased cost of raising children in a wealthy nation versus the decreasing benefit to themselves.

Europe is also looking at the same demographic trend - parts Germany are returning to the wild due to lack of population. In the US, if immigration is excluded, the birth rate is barely sufficient to replace the population lost to death. China and India are both projected to stop and reverse their population growth rates during this century as they become increasingly prosperous. Disregarding possible technological achievements such as the end of aging, the world's population is likely to be smaller in 2100 than it was in 2000.
