Fertility and Population Growth

The total fertility rate (TFR) of 1.51 children per woman is below the replacement level of 2.1, which without immigration leads to population decline over time. The population is roughly stable at a rate of 0.18% per year. This moderate growth rate reflects a balance between natural increase and migration patterns.
