A Dutch study found that living in a green environment was positively related to the health of residents. The effect was somewhat stronger for less-educated residents, suggesting that this group is more sensitive to local physical environmental characteristics. The relationship between greenspace and fewer self-reported symptoms was also stronger for housewives and the elderly, two groups assumed to spend more time in the vicinity of their homes.
