General information

This data visualisation tool focused on housing data has been developed as part of a programme led by Birmingham City Council (BCC) funded by the Cabinet Office Release of Data Fund.

It is part of a wider initiative to develop a Birmingham Data & Skills Hub to encourage citizens, communities and third sector organisations to understand the value of open data in highlighting, analysing, helping address community issues. Data from BCC visualized here can be found on the Birmingham Data Factory website.

We are grateful to community groups in Castle Vale, Basall Heath and Sparkbrook for their inputs into the project. A key issue they raised that we have tried to address is the difficulty community groups have in seeing data at a very local level. This tool allows you to see data down to Lower Super Output Areas – which on average in England and Wales cover 672 households and 1614 people. See below for further information on data and sources used.

Areas used on the Maps

This area is used to define a general area within the city of Birmingham. The idea is that most users will identify with a particular area at this scale and provide an easy entry point into the smaller areas used in the application.

Wards are also used to provide an overview of some of the general topics and statistics across the whole city. This allows the user to view a city wide picture for a topic of interest and then, by clicking on one of the wards, dig deeper into that area by creating a neighbourhood made up of LSOAs

ONS Reference for Electoral wards/divisions (Council wards)

LSOA - Lower Super Output Area, these geographical areas are a creation of the ONS and the smallest area that they collect statistics for. They are made up of between 400 and 1,200 house holds.

LSOAs are not directly linked to Council Wards, however the LSOAs that appear for each Ward described as either being 'covered by' or 'overlapping with' the Ward boundary line retrieved from the MapIt API

Using LSOAs allows the user to view the statistical information at the most local level whilest providing a sufficient amount of anonymity for people the information describes.

Notes:

Take home pay is calculated using the following formula:
weekly gross (the value provided in the dataset)
Annual gross = Weekly gross * 52
Taxable income = Annual gross - 10,000
Income tax = Taxable income * 0.2 (20%) NB: for simplicity only basic rate tax is used
National Insurance = Weekly gross * 0.106 (10.6%) NB: assumed NI code D and again the same rate is applied to all income levels
Weekly net = Weekly gross - Income tax - National Insurance;
Monthly net = (Weekly net / 7) * 31

Notes:

The rental data is based on the 100 most recent listings available on Zoopla within 1 mile of the area's postcode, this is cached for a week before being refreshed. Each clickable area on the map, both Wards and LSOAs, have an example postcode listed against retrieved from the MapIt API, this is used for the search from the Zoopla API.

Notes:

The rental data shown is the average rent for council properties of different sizes (by number of bedrooms) in each LSOA as at (BCC to add date). Where combinations of LSOAs are selected, the data shows averages across the larger area.

Social Housing

Notes:

Social housing is defined here as housing rented from housing associations, nowadays known as ‘private registered providers’. Unfortunately, data on housing association rents is not open. The only data we can get is a single figure for average rent across Birmingham for all types of property, however large or small. This is disappointing and means the comparison with council and private rents is not very useful.

Notes:

The Indices of Deprivation 2010 (ID 2010) is a deprivation index at the small area level, created by the British Department for Communities and Local Government (DCLG) and released on 24 March 2011. It follows the ID2007 and because much of the datasets are the same or similar between indices allows a comparison of "relative deprivation" of an area between the two indices.
