The lines for lead paint and for the deprivation index rise from left to right, the deprivation line most steeply.",
  "caption": "The urban-industrial line starts highest and ends lowest, at {fact:asth_pc1_t20} in the top twentieth, while the lead-paint line rises from {fact:asth_ldp_t1} to {fact:asth_ldp_t20} and the deprivation line from {fact:asth_adi_t1} to {fact:asth_adi_t20}. CDC PLACES prevalence is a model-based estimate that uses the age, race, ethnicity and education of a tract's residents, so the deprivation line is partly mechanical.
