Aim

The aim of this project is to visualize the population density of states in Nigeria using a choropleth map.

Data Source

The population dataset was obtained from WorldPop. It records the spatial distribution of the population in 2020 with the country's total adjusted to match the corresponding UNPD estimate, Nigeria.

The state boundary data was obtained from Diva-GIS

Result

Using the method of zonal statistics, the sum of population data points within each state boundary was calculated and stored in a new column. The map was further classified into 4 classes of unequal intervals to capture major data shifts. The top ten most populated states are displayed in a table to provide further data insights.

The colour choice was influenced by the country's flag colours; Green and White.
