Hi,
I dont know specifically for BLR, but this might be a start:
It might be useful to see code I used to compute the same statistic for
Pune wards:
from area import area
def areas(gjson):
A = []
for entry in gjson['features']:
geom = entry['geometry']
A += [area(geom) if geom['type'] == 'Polygon' else 0]
return A
wardcrds = [avg_coords([ward]) for ward in wards['features']] # wards is a
geojson object (dict/json)
wardarea = areas(wards)
wardpops = [get_ward_pop(ward['properties']['prabhag'])
for ward in wards['features']]
warddens = np.array([pop/ar for pop, ar in zip(wardpops, wardarea)])
the notebook is linked here:

<http://s000.tinyupload.com/index.php?file_id=00023234941653471825>
Approach:
- Use 2011 census data to get population
- use an existing geojson mapping of wards
- Use python package `area` to compute area of the region
example usage and heatmap visualization using leafletJS is available online

similar can be done for districts
