  • The average number of sunlight hours each city gets per year
  • The average number of hours spent working in each city, to determine how much leisure time people have.
  • The number of free outdoor attractions in each city, to determine how easily people can get outdoors regardless of whether or not they have a garden.
  • The average number of sleep hours in each city, to correlate sunlight exposure to better quality of sleep
