Using LTA’s RoadSectionLine, I classified the roads into expressways, minor road and major road by creating a new field called “Road Type”. Major roads have the word roads contained in their name. I categorized them using the same method as above.

Part 2

After downloading the csv file by age group, I cleaned the data on excel to remain the relevant fields and named it as “Population by age and subzone”, which I imported into QGIS. I then joined subzone and the aforementioned csv file together and formed the relevant choropleth maps.

Choropleth Map for Population Above 65 2018

Choropleth Map for Population Above 65 in 2010

Above 65 2010.png











Based on the choropleth maps, we see that there are a lot more subzones with aging population in 2018 as compared to 2010. The highest number of ageing population in a subzone has also increased.

Choropleth Map for Proportion of Population above 65 in 2018

For proportion of population above 65, the same conclusion can be made based on the choropleth map.

Changes in Population above 65

This map mainly summarizes the before choropleth maps. We see that there are many subzones with increases in aging populations.
