Table 1. Data descriptions of variables used in analysis.

Variable		Description
Dog Vaccinations	Vi,t	Number of dogs vaccinated against rabies (1,000s). (REDIPRA 1992–2006). [13]
Dog Rabies Cases	$R_{i,t}^D$	Number of reported confirmed dog rabies cases (REDIPRA 1992–2006). [13]
Reported Exposures	$E_{i,t}^H$	Number of people reported to have had physical contact with a suspected rabid animal (REDIPRA 1992–2006). [13]
PEP Completions	Pi,t	Number of people who completed a full course of PEP (REDIPRA 1992–2006). [13]

Rural Population	$H_{i,t}^r$	$\left({\mathrm{H}}_{\mathrm{i},\mathrm{t}}-{\mathrm{H}}_{\mathrm{i},\mathrm{t}}^{\mathrm{u}\mathrm{r}\mathrm{b}}\right)$, where Hi,t is Human Population, total, World Bank indicator codes: SP.POP.TOTL. (1,000s). [23]
Income	Ii,t	GDP per Capita, PPP, constant 2011 international $. World Bank Indicator Code NY.GDP.PCAP.PP.KD. [23]
Health Expenditures	Xi,t	Health expenditure per capita, PPP constant 2011 international $. World Bank Indicator Code SH.XPD.PCAP.PP.KD. [23]
