  1. 1Coefficient estimates from multivariate linear regression (when all explanatory variables enter simultaneously). Robust standard errors clustered at CBG level in parentheses below coefficient estimates. *P < 0.1 **P < 0.05 ***P < 0.01
  2. 2High variety indices include all produce types listed in Table 1.
  3. 3Basic fruit index only includes apples, bananas, and oranges. Basic vegetable index only includes carrots, lettuce, onion, potatoes and tomatoes.
  4. 4 Taken in natural logarithm.
