Impact of TSPs (100 µg/m3) on health outcomes using conventional strategy (ordinary least squares)
| Dependent variable | (1) | (2) |
| ln(All cause mortality rate) | 0.03* (0.01) | 0.03** (0.01) |
| ln(Cardiorespiratory mortality rate) | 0.04** (0.02) | 0.04** (0.02) |
| ln(Noncardiorespiratory mortality rate) | 0.01 (0.02) | 0.01 (0.02) |
| Life expectancy, y | −0.54** (0.26) | −0.52** (0.23) |
| Climate controls | No | Yes |
| Census and DSP controls | No | Yes |
n = 125. Each cell in the table represents the coefficient from a separate regression, and heteroskedastic-consistent SEs are reported in parentheses. The cardiorespiratory illnesses are heart disease, stroke, lung cancer and other respiratory illnesses. The noncardiorespiratory-related illnesses are violence, cancers other than lung, and all other causes. Models in column (2) include demographic controls and climate controls reported in Table 1. Regressions are weighted by the population at the DSP location. *Significant at 10%, **significant at 5%, ***significant at 1%.
