India's Population Data

Population

The population series was pulled from the DevInfo database. This source has a shorter time series of population by state, but it will be more up to date than alternative sources which is best for model initialization. The state of Telangana had to be estimated in this series because the data for Andhra Pradesh includes both Telangana and Andhra Pradesh. Unlike other population data sources there is not district level population data available in the DevInfo database. To estimate Telangana's population, district-level population data from the 2011 census was found for the districts that make up the state of Telangana. The sum of the districts that make up Telangana was subtracted from the state of Andhra Pradesh's population from the 2011 census. From the two state population estimates, a ratio of state population relative to the total population was found. This ratio was then used to estimate the appropriate populations for Andhra Pradesh and Telangana from the DevInfo database. 

State	2011 Population	2011 Population Ratio
Telangana	30.987	0.4066
Andhra Pradesh	45.223	0.5934

 

Typically, the official data source for subnational population is the national census. However, India's Census is conducted every ten years and there appears to not be any annual estimates available from this source. This makes the census data quite out of data being that the last census was conducted in 2011, and we will not be able to update this until after the 2021 census. Thus an alternative source is being used to ensure that population data is available to be updated more frequently than every decade.

Age-Sex Cohorts

The age-sex cohort data came from the 2011 Census. This data was published in single year cohorts and was aggregated into the five-year cohorts that are used in the model.
