IS TREE CONDITION RELATED TO INCOME LEVELS?
Tree Condition in Six Tracts Surprisingly, as Figure 7 shows, the six areas shared very similar mean street tree condition levels. Moreover, mean street tree condition showed no significant relationship to income; tree condition neither increased nor decreased with median household income6. Figure 7 shows the absence of any statistical relationship between median household income and average tree condition; the line is relatively flat across all income levels and the average condition scores do not vary by median household income.
