1Coefficient estimates from univariate linear regression (when explanatory variables enter one at a time). Robust standard errors clustered at CBG level in parentheses below coefficient estimates. *P < 0.1 **P < 0.05 ***P < 0.01

2High variety indices include all produce types listed in Table 1.

3Basic fruit index only includes apples, bananas, and oranges. Basic vegetable index only includes carrots, lettuce, onion, potatoes and tomatoes.

4 Taken in natural logarithm.
