Table 8 lists the country-level CPI and PPP that are used to intertemporally deflate the international poverty line to local currency units. For example, to calculate the international poverty line expressed in Bangladeshi takas for the year 2010 so that it can be applied to the 2010 HIES, we do the following. First, the 2011 PPP for Bangladesh (24.85) is multiplied by the international poverty line ($1.9), and this is then deflated using the intertemporal deflator (0.9). Thus, the daily international poverty line expressed in local currency comes out to be: 1.9 × 24.85 × 0.9 = 42.65 takas.

na = not available, PPP = purchasing power parity.
aAfghanistan is not included in PovcalNet because it lacks a PPP deflator, and the government is not comfortable using a regression-based PPP.
Note: All countries use the consumer price index except for Bangladesh, which uses the Basic Need Price Index.
