Subnational HDI (v7.0)
Sub-national Gender Development Index (SGDI).
To create the SGDI, separate female and male versions of the Subnational Human Development Index (SHDI) were constructed. To make these gender-specific SHDIs, exactly the same procedure was used as with the general SHDI, but using gender specific versions of the indicators for education, health and standard of living. The SGDI was subsequently created by dividing the female version of the SHDI by the male version of the SHDI. An SGDI value below one indicates gender inequality to the disadvantage of females. Values above one indicate gender inequality to the disadvantage of males. A value of one indicates gender parity.
The SHDI is an average of the subnational values of three dimensions: education, health and standard of living. To compute the SHDI on the basis of the three dimension indices, the geometric mean of the three indices is taken.
Three major data sources were used to create the SHDI database: statistical offices (including Eurostat, the statistical office of the European Union), the Area Database of the Global Data Lab, and data from the HDI website of the Human Development Report Office of the United Nations Development Program.
Given that household surveys and censuses are not held every year, for many countries the indicators are only available for a restricted number of years. To obtain their values for the whole period 1990–2017, the missing information was estimated by interpolation or extrapolation techniques. This estimation process was facilitated by the fact that the UNDP Database contains the national values for all four indicators for each year in this period, which means that only the subnational variation had to be interpolated or extrapolated.
