Data mania!

How data can help you understand your community

April 2016

By Sonia Bussu, research and learning co-ordinator, Local Trust

Local Trust and NIHR School of Public Health Research have been doing a lot of work to map Census 2011 and other government data onto the very small boundaries of the Big Local areas. We’ve now estimated area and demographic characteristics for all 150 Big Local areas.  

Some Big Local areas have asked us for this data to help them understand the demographics of their community: things like residents’ age, health and ethnic groups. This kind of knowledge can help identify and tailor activities to include when writing or revising a Big Local plan. 

Referring to data could also help you challenge assumptions about your area and start a conversation with your Big Local residents.

The data reports for each area give the most accurate data we can get for Big Local areas, but it’s important to keep in mind that these are still estimates, and what’s more they are estimates for small areas– and with statistics the smaller the numbers the higher the margin of error.

Data is always only part of the story. Rather than trusting it blindly, it’s important to take it with a pinch of salt and use our collective intelligence and judgement to make sense of it. As Mark Twain once said, “Facts are stubborn, but statistics are more pliable”.

So what data is on offer?

Each area report contains the following:

  • total population count
  • age
  • ethnic groups
  • marital and civil partnership status
  • sex
  • economic activity
  • qualifications
  • households by deprivation status
  • occupation
  • tenure
  • general health (self-reported)
  • long-term health problem or disability
  • unpaid care
  • religious beliefs
  • country of birth
  • language
  • multiple-deprivation score for 2010 and 2015
  • traffic accidents.
