Analysing the BBMP Elections

The Bruhat Bengaluru Mahanagara Palike (BBMP) went to polls on Saturday, and votes were counted today. The BJP has retained its majority in the house, winning 100 out of 198 available seats. While this is a downer compared to the 113 seats they had won in the previous elections in 2010, the fact that they have won despite being in opposition in the state is a significant achievement.

Based on data put out by Citizen Matters, here is some rudimentary analysis. The first is a choropleth of where each party has performed. Note that this is likely to be misleading since constituencies with large areas are over-represented, but this can give you a good picture.

Notice that there are a few “bands” where the BJP has performed really well. There is the south-western part of the city that it has literally swept, and it has done well in the south-eastern and northern suburbs, too. And the party hasn’t done too well in the north-west, the traditional “cantonment” area.

We can get a better picture of this by looking at the choropleths by assembly constituency. These shapes might be familiar to regular readers of the blog since I’d done one post on gerrymandering.


This tells you where each party has done well. As was evident from the first figure, the BJP has done rather well in Basavanagudi, Jayanagar and Padmanabhanagar in “traditional South Bangalore” and blanked out in Pulakeshi Nagar in the cantonment. In fact, if you try to correlate these results with that of the last Assembly elections, the correlation is rather strong. Most constituencies have gone the way of the assembly segments they are part of.

Then there is the issue of reservation – there were a lot of murmurs that the Congress party which is in power in the state changed the reservations to suit itself. Yet, there are a few interesting factoids that indicate that the new set of reservations were rather logical.

The next two graphs show the distribution of SC and ST populations respectively as a function of the reservations of the constituencies (population data from

Rplot03 Rplot02Notice that the constituencies reserved for SCs and STs are among those that have the highest SC and ST populations respectively. The trick in gerrymandering was in terms of distributions between general and OBC constituencies, and among women.

I could put the performance of different parties by reservation categories, and on whether the reservation of a constituency has changed has any effect on results, but (un)fortunately, there aren’t any trends, and consequently there is little information content. Hence I won’t bother putting them in.

Nevertheless, these have been extremely interesting elections. All the postponement, all the drama and court case, and finally the underdog (based on previous trends) winning. Yet, given the structure of the corporation, there is little hope that much good will come of the city in the coming years. And there is nothing in the election results that can alter this.
