Hypothesis
How have food deserts evolved in London, Ontario since the 1960s?
Conclusion
Low-income residents in London’s inner-city neighborhoods have significantly poorer access to supermarkets compared to wealthier residents, and this disparity has worsened over time.
Supporting Evidence
- In 1961, over 75% of London’s inner-city population lived within 1 kilometer of a supermarket.
- By 2005, that number had dropped to less than 20%.
- The study is the first known historical analysis of food deserts over time.
Takeaway
In the past, it was easier for people to get to grocery stores, but now many low-income neighborhoods don't have supermarkets nearby, which can make it hard for families to find healthy food.
Methodology
The study used geographic information systems (GIS) to map supermarket locations from 1961 and 2005 and assessed access in relation to neighborhood characteristics.
Limitations
The study did not factor in car trips to supermarkets, which may affect access.
Participant Demographics
The study focused on residents of London, Ontario, particularly low-income individuals in inner-city neighborhoods.
