1) Gym/health clubs: How many gyms or clubs there are per person.
2) Bike friendliness: How accessible roads and community spaces are for cyclists.
3) Walk friendliness: How easy it is for a pedestrian to get around.
4) Access to healthy food: What percent of people could get nutritious food readily and with ease.
5) Healthy weight: Percentage of adults who are of healthy weight.
6) Wellbeing: The general quality of life for people living in that city.
