Bristol Government: Open Data Initiative

Bristol City Council (BCC) is now publishing some of their data sets online as part of the Open Data initiative.
This is a VERY positive move and I too hope that this leads to the development of ‘new’ solutions to the city’s problems.
More information can be found here: https://opendata.bristol.gov.uk

The Tableau Viz below uses the Quality of Life Indicators data from across Bristol. This is available from the BCC website. The data set has a set of questions (about 540) asked across the different wards in Bristol (about 35) on a yearly basis starting from 2005 till 2013. Obviously data is not available across all the dimensions, for example the question:
“% respondents who travel for shopping by bus” for the Redland ward is available only from 2006-2010.

The raw data from the Open Data website was processed using Apache Spark’s Java Libraries. This was then dumped into a data file which was imported into Tableau.

The heat map below plots the regression slope of the survey results over the years (beta) against the Questions and Wards.
Criteria for beta calculation: minimum three years data should be available.
