The rate of natural increase gives demographers an idea of how a region's population is shifting over time. RNI excludes in-migration and out-migration, giving an indication of population growth based only on births and deaths. Comparing natural population change with total population change shows

Government attempts to shape the RNI of a region or country are common around the world. Policies can either encourage or discourage an increase in birth rates. For example, during the COVID-19 crisis
Singapore offered families a “pandemic baby bonus” to encourage a higher birth rate, therefore

This RNI gives demographers an insight into how a region's population is evolving, and these analyses can inform government attempts to shape RNI.
