From the Executive Summary:
The focus of this report is on the hidden and often neglected
plight of the urban poor. For the purpose of this analysis, the “urban
poor” are defined as the bottom quintile (i.e., the poorest 20 percent
of urban households). The “urban rich,” in contrast, are the top
quintile (i.e., the richest 20 percent). The “urban survival gap” is
key metric used throughout. For this report, it refers to relative (not
absolute) inequity in child survival chances and is given by the ratio
between these two groups (i.e., the under-5 mortality rate (U5MR)
for the urban poorest is divided by the U5MR for the urban richest).
A relative difference of 2.0, for example, means the poorest urban
children are twice as likely as the richest urban children to die before
reaching age 5.
