Analysis

Work with a measure over time and across areas: time series, rankings, change between periods, comparisons, totals and conversions.

• List reviewed conversionsSee which measure, source and analysis-boundary combinations the Atlas has reviewed as safe to convert. A crosswalk appearing in the catalogue alone is not an approval to use it for analysis.get/analysis-geographies
• Preflight an analysis conversionCheck whether one published period can be compared on a named analysis boundary before retrieving data. The response is a plan: it selects no data and never silently chooses between source partitions.get/analysis:plan
• Check conversion supportInspect the reviewed conversion paths for one measure on one analysis boundary. Use it to discover supported source partitions before asking for a preflight plan.get/measures/{measure-id}/conversion-support
• Add up a measureGet a total over a group of areas, such as a country, a combined authority, a county or a named location like Greater Manchester. Shares with a published weight are averaged instead. It only combines values where the result genuinely means something.get/data/{measure-id}/aggregate
• Convert to other areasRegroup a measure onto a different set of areas, such as wards up to local authorities, using a crosswalk you choose. Only counts can be converted, because converting works by adding values up.get/data/{measure-id}/convert
• Get a time seriesGet every value for one area, oldest first. Usually these are published source-exact values; a reviewed analysis geography can instead return values explicitly regrouped onto one named boundary frame.get/data/{measure-id}/series
• Rank areasRank every area by a measure for one period: the most populous wards, the lowest emissions and so on. Tied areas share a rank, so you'll see 1, 1, 3.get/data/{measure-id}/rankings
• Rank areas by changeFind where things changed most between two periods, such as where population grew fastest between 2011 and 2022. Add place to see one area's change and where it ranks against all the others.get/data/{measure-id}/change
• Compare two areasPut two areas side by side for one period and get both values and the difference between them.get/data/{measure-id}/compare
