In a study by Mika R. Moran, Daniel A. Rodriguez, and colleagues, residents of Caracas, Venezuela, and of Fortaleza, Brazil, were surveyed about parks in their cities. Of the 1,043 respondents from Caracas, 44.7% indicated that they use the city's parks, and of the 938 respondents from Fortaleza, 35.7% indicated using city parks. It may be tempting to assume the difference is due to different levels of access to parks: however, given that the percentage of Caracas respondents who reported living within a 10-minute walk of a park was much lower than that reported by Fortaleza respondents, greater proximity alone can’t explain the difference in park use.
