Chapter 6 quantitatively tests the theoretical framework with survey data from 111 squatter settlements. I find that party worker density is positive and statistically significant in its association with paved road coverage, streetlight coverage, municipal trash removal, and the provision of government medical camps. These findings hold when controlling for a wide range of potential confounders and are robust to several model specifications and post-estimation tests. Read alongside my qualitative findings, these statistical relationships provide further evidence that denser concentrations of party workers are associated with higher levels of public service provision.
