Part 4/11:
Demographic overlay maps reveal that regions with the highest heat exposure often house elderly populations—particularly in older public housing estates from the 1970s and 1980s—placing vulnerable residents at greater risk of heat-related illnesses like heat stroke.
An economic dimension emerges as well: low-income households, especially in rental flats, tend to lack resources such as air conditioning, increasing their susceptibility to heat stress.
By overlaying these maps, researchers identify neighborhoods like Jalan Basah, Ghim Moh, and parts of Jurong West as most vulnerable due to the combination of high temperatures, dense populations of elderly residents, and economic hardship.
