| “Singapore Residents by Planning Area/Subzone, Age Group and Sex, June 2000 - 2018” from Department of Statistics Singapore. |
Layer: res Processing: 1.Singapore's Aged Population (65+) in 2010 created new filtered layer with age 65+ and year = 2010. New column is created and caculated as the sum of the 65+ population for 2010. Join technique is used in the MP14 layer to join the Area Name.  2010 65+ Map
2.Singapore's Aged Population (65+) in 2018 created new filtered layer with age 65+ and year = 2018. New column is created and caculated as the sum of the 65+ population for 2018. Join technique is used in the new MP14 layer to join the Area Name.  2018 65+ Map
We are looking at the ratio of population that is above 65 and the total residence number The observation is that the 1)downtown area has a higher proportion of aged population. 2)North region also has high proportion of senior polulaiton.  Proportion of Aged population of 2018
4.Proportion of Singapore's Aged Population in 2018 When we look at 2010 and 2018 map in terms of the aged population ratio that has been explained earlier. we can see that the 2018 statistics is more well spread as seen by the dark color block compared to that of 2010. This might be an indication of the aging population.  Proportion of Aged population of 2018
