The decomposition tool, available publicly and developed with help from the DevInfo Support Group, allows users to select a geographic location and instantly have access to United Nations estimates and projections for indicators such as Total Fertility (children per woman) and Population Projections. Below is an example of Population Projections for Rwanda:
The red line at the bottom shows the Standard Projections, which includes the effects of high fertility, mortality, migration and momentum. The green line, however, shows the Replacement Projections in Rwanda; this means that the data only takes into consideration the current national young age structure, as well as changing mortality and migration patterns. These are further explained by accessing the tool.
“Our hope is that country offices and regional offices will use this information to support their policy decisions and programme planning with a balance between demographic change and their social, economic and environmental goals. We also welcome them to help us ensure that the most recent population data is made available,” says Mengjia Liang, Monitoring and Evaluation Analyst at UNFPA. Indeed, UNFPA country offices can be granted the ability to enter information from their latest round of census and keep data from the decomposition tool as recent as possible.
In the next decades, broad policy options will need to be adopted on the national and subnational levels to adjust fertility rates and address the momentum of population growth. The decomposition tool and its many features, including the ability to export an already formatted report for all geographical levels available (download the report for Rwanda by clicking here), will certainly support these important efforts by bolstering access to information and facilitating data-driven decision-making.
