Pune city in 2011 had 144 electoral wards, on the basis of which census data was released, including variables such as population (total, male and female), Scheduled Caste population (total, male and female), Scheduled Tribes (total, male and female) and Children below 6 (total, male and female). After plenty of effort we have been able to obtain and visualize this and doesn’t it look beautiful. As you would guess the core city has the highest population density of more than 50,000 per sq km, whereas the South and South western parts of the city towards Kothrud also have a high density of >10,000 per sq km. In comparison, the North Western, North Eastern and South Eastern parts of the city are relatively sparsely populated with <5000 per sq km. The rest of the data, i.e. population below 6, Scheduled castes and Scheduled tribes was not visualized since their values are not actual but computed by a general rule. The SC population in each ward is assumed to be 18.6% of the ward’s total population, the ST population is 3.5%, and children below 6 are taken to be 12.9% of the total population. Similarly the Female:Male ratio is not actual but computed, based on averages for each sub-group. The raw data can be found on the PMC’s website here. The same raw data and derived data for population densities in an excelsheet can be found here
Hovering on each of the wards should display a box with information on population and population density.
Note: Area for each ward was calculated in QGIS using EPSG:3857, web Pseudo mercator projection. This shapefile, of the 144 wards, corresponding to the 2011 ward names shows the total area of Pune as 277 sq km, whereas the official figures for 2011 (Pune district census handbook) says 430 sq km. As per the 2001 census however the area of Pune was 243 sq kms.
This mystery remains unsolved for now
