Fig. 5: Correlation of the PDI with related indices and GDP per capita.
From: An index of access to essential infrastructure to identify where physical distancing is impossible
Scatter plot of the PDI (using the latest available Demographic Health Survey of a country) against the infectious disease vulnerability index (a)26; the WHO international health regulations index (b)25; the home environment for protection index (c)29; and the country's GDP (d)2. Note that a high PDI implies a lack of essential private infrastructure, and hence, high risk of disease transmission; accordingly, countries in the top of boxes have a lack of private infrastructure, and hence, lack the capacity to limit disease transmission. Moreover, note that for the infectious disease vulnerability index, the WHO international health regulations index, and the home environment for protection index, a higher value indicates a better preparedness, or protection. In addition, ISO-3 country codes are used to abbreviate the countries in this figure. See Supplementary Table 2.1 for details on the ISO-3 country code.
