Dataset description

<span style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; color:rgb(0, 0, 0); font-size:17px;'>This is an exact fit lookup file between Lower layer Super Output Areas as at December 2011 and Lower layer Super Output Areas as at December 2021 and Local Authority Districts as at December 2022 in England and Wales. This product has been provided with a 'change indicator' field, that define the lookup between 2011 and 2021 LSOA. This field indicates which super output areas have changed between 2011 and 2021. </span><div style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'><font color='#000000' style='font-family:inherit;'><span style='font-family:inherit; font-size:17px;'><br /></span></font></div><div style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'><font color='#000000' style='font-family:inherit;'><span style='font-family:inherit; font-size:17px;'>This is a version 3 of the lookup where the Change Indicator has been changed from splits to complex in less than 10 LSOAs and four 2011 LSOAs - Shepway 014E to Shepway 014H corrected to Shepway 015A - Shepway 015D<br /></span></font><div style='font-family:inherit;'><span style='font-family:inherit; color:rgb(0, 0, 0); font-size:17px;'><br /></span></div><div style='font-family:inherit;'><span style='font-family:inherit; color:rgb(0, 0, 0); font-size:17px;'>There are four designated categories to describe the changes, and these are as follows:</span></div><div style='font-family:inherit;'><span style='font-family:inherit; color:rgb(0, 0, 0); font-size:17px;'>U - No Change from 2011 to 2021. This means that direct comparisons can be made between these 2011 and 2021 LSOA.</span></div><div style='font-family:inherit;'><span style='font-family:inherit; color:rgb(0, 0, 0); font-size:17px;'>S - Split. This means that the 2011 LSOA has been split into two or more 2021 LSOA. There will be one record for each of the 2021 LSOA that the 2011 LSOA has been split into. This means direct comparisons can be made between estimates for the single 2011 LSOA and the estimates from the aggregated 2021 LSOA.</span></div><div style='font-family:inherit;'><span style='font-family:inherit; color:rgb(0, 0, 0); font-size:17px;'>M - Merged. 2011 LSOA have been merged with another one or more 2011 LSOA to form a single 2021 LSOA. This means direct comparisons can be made between the aggregated 2011 LSOAs’ estimates and the single 2021 LSOA’s estimates. </span></div><div style='font-family:inherit;'><span style='font-family:inherit; color:rgb(0, 0, 0); font-size:17px;'>X - The relationship between 2011 and 2021 LSOA is irregular and fragmented. This has occurred where 2011 LSOA have been redesigned because of local authority district boundary changes, or to improve their social homogeneity. These can’t be easily mapped to equivalent 2021 LSOA like the regular splits (S) and merges (M), and therefore like for like comparisons of estimates for 2011 LSOA and 2021 LSOA are not possible.  </span></div><div style='font-family:inherit;'><span style='font-family:inherit; color:rgb(0, 0, 0); font-size:17px;'><br /></span></div><div style='font-family:inherit;'><span style='font-family:inherit; color:rgb(0, 0, 0); font-size:17px;'>Field Names – LSOA11CD, LSOA11NM, CHGIND, LSOA21CD, LSOA21NM, LAD22CD, LAD22NM, LAD22NMW</span></div><div style='font-family:inherit;'><span style='font-family:inherit; color:rgb(0, 0, 0); font-size:17px;'>Field Types – Text, Text, Text, Text, Text, Text, Text, Text</span></div><div style='font-family:inherit;'><span style='font-family:inherit; color:rgb(0, 0, 0); font-size:17px;'>Field Lengths – 9, 33, 1, 9, 40, 9, 35, 24</span></div></div>

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

api.store is built and operated by Apitalks s.r.o. Company details and a direct contact path are linked in the footer for vendor checks and procurement review.
Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.
Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.
Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.
Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
