Although these models only refer to 2013 and 2014 the similarity in results (and few other quick tests I have undertaken, especially omitted variable bias and multicollinearity) point at a correlation between greenspace and health. To derive causation is not, however, that straightforward: it has to be assumed that being unwell does not cause people to move further away from greenspace. Holding a degree, being healthy and younger seem to be connected to greenspace usage. Unemployed individuals seem to use public parks more than other citizens. Greenspace usage is also deeply correlated to proximity and satisfaction with greenspace quality. Use is also less frequent among those with lower income, but only in 2013. It is worth noticing that greenspace proximity is negatively correlated to low income (see tables below); low earners are 3.5-4% less likely to have greenspace access close by.
