What data is out there about Councillors and MPs?

Join us on Tuesday 1 October for Digging the Data: MPs, Councillors and Elections where we’ll be exploring the fascinating world of political representation in the UK. Register here.

The July election brought big changes across the UK, as did the local elections before them in May. But what data is out there about our political representatives, and what can this data show us?

This post introduces some of the resources out here, as well as introducing some work we’ve been doing to make more data openly available. We have focussed on England, where we are based.

How do we know who’s in charge?

It can be confusing to wrap your head around the different representatives we get to choose. This guidance on local government structure and elections gives a handy introduction to some of the people we get to elect in England.

There is a lot of information out there about our elected representatives, but it isn’t always easy to get your hands on – particularly for local government.

What have we been up to?

Over the last few months we’ve been using support from the Manchester Statistical Society to open up more data about Councillors. This work is an updating of something we created a few years back.

The aim of this work is to make it easier to find out the results of council elections across England, and to help people explore the relationship between the political make-up of local areas and how deprived these areas are in comparison to others.

A series of plots shaped to show the profile of relative deprivation in local authorities. The local authorities are ordered from most deprived to least deprived, and coloured to show their political control.
The visualisation above shows how local political control in October 2019 varies across areas with different profiles of relative deprivation. This blog explains more about the visualisation and our method.

As the results of Council elections are published individually by each Council is can be hard to get a detailed picture of local election results across England as a whole. In previous years we had to rely on scraping this data from council websites. This year we’ve not had to rely on scraping the data alone as Open Council Data have collated this data themselves and made it freely available.

We then linked results from individual wards with data on the relative deprivation of smaller areas called LSOAs. This data was taken from the English Indices of Deprivation. LSOAs and wards don’t neatly match up, but there is an ONS dataset that uses ‘best-fitting’ to link LSOAs up with wards. Using this, we have created a dataset that allows you to explore the relationship between the relative deprivation of local areas across England, and ward-level election results matched to these areas.

How can you explore the data?

You can freely download this dataset of local election results linked to levels of relative deprivation on our GitHub, including information about how it was created and what it can be used for.

You can also access datasets we created in previous years, including the script used to scrape the data.

We have also been experimenting with ways of showing trend in this data, such as the draft graph below. There will be more coming soon.

A bar chart showing the mean level of representation for the 3 main parties for LSOAs in each decile of the English IMD. This is a draft which we are intending to publish in an accessible format in the future.
The English IMD groups small areas called LSOAs into 10 equal deciles based on their relative levels of deprivation. This graph shows the average proportion of councillors from the Conservatives, Labour and the Liberal Democrats elected in LSOAs that fall in each of these deciles. Decile 1 has the highest level of relative deprivation, and 10 has the lowest.

What else is out there?

There are handy sources of data out there, and some great examples of making this easy to explore:

We will be exploring some of these resources (and others) at our event on the 1st October, making connections between data and each other, and seeing what we can find out and create. If you’d like to learn more then come along.

Not based nearby but want to connect about the work we are doing? Do drop us an email at hello@opendatamanchester.org.uk or you can sign up to our monthly newsletter.

To keep this blog up to date we may add in some more resources over time. If there is something great we’ve missed then let us know. (This blog was edited on 30th September & 4th October 2024 to add in further resources, as well as making sections about our work more concise.)
