For both maps, there is a large number of aged population in the east side of Singapore as the darker the colours , the more the ageing population
There is also an increasing number of aged population from 2010 - 2018

The proportion of aged population is more spreaded out across Singapore
There is also an increasing number of aged proportion from 2010 - 2018

  • Percentage change of aged population between 2010 and 2018

  • Discussion


For the data for age population 2010 & 2018 , a lot of data cleaning is involve, i reference the data layout in excel with one of the take home exercise where we are given the age population excel data set . One of the challenge that I face that the column for all the values are recognize by qgis as string format due to it having a comma e.g. '1,200', once i change the column properties to make it 'general' e.g. '1200', qgis recognize it as integer / double which solves the problem.
For Aged population (+65) in 2010 and 2018, I added the columns from 60-65 till 85 & over.
For Proportional of aged population in 2010 and 2018, I use Aged population (+65) / The total age columns * 100 to get the percentage
For the percentage change of age population 2010 & 2018, I joined the shape file of 2008 and 2014 Master Plan , and also the excel file of 2010 and 2018 to calculate the percentage change.
