In case you didn't get the memo, we've got a big @Census2021 data release coming this Wednesday (2 November) at 9:30am. A quick 🧵 on what to expect... 1/5
This next data release will include datasets on the topic of "demography and migration". It is the first of nine topic summary data releases, and is the first @Census2021 release with data down to a neighbourhood level (AKA "output area" level) census.gov.uk/census-2021-re… 2/5
Specifically, you can expect to find data for variables including population density, median age, sex, household size and deprivation, marital status, passports held, and length of residence in the UK 3/5
We're particuarly excited about Wednesday's release because we'll be going live with a new #CensusMaps tool that will allow you to explore all of this data on an interactive map right down to neighbourhood level (THIS SCREENSHOT IS NOT ACTUAL DATA!) ons.gov.uk/releases/censu… 4/5
🚨 BREAKING 🚨
There's a brand new @Census2021 release this morning with data covering England and Wales right down to a neighbourhood level. You can explore the data using our brand new #CensusMaps tool, but here's a 🧵 with a few highlights... ons.gov.uk/census/maps 1/9
MEDIAN (AVERAGE) AGE
The oldest local authority in the country on Census day 2021 was North Norfolk (54 years) and the youngest was Tower Hamlets (30 years). At neighbourhood (MSOA) level, average ages ranged from 20 years to 66 years ons.gov.uk/census/maps/ch… 2/9
MARRIAGE & CIVIL PARTNERSHIPS
There was a huge variation across England and Wales in the proportion people who were married (incl. civil partnerships). The highest % in Wokingham (55.0%) was almost double the lowest in Lambeth (25.6%) ons.gov.uk/census/maps/ch… 3/9
1/ Ever wondered how your local area has changed over half a century? Today, @ONS is releasing an interactive article covering some of the most interesting changes between 1961 and 2011 England & Wales censuses right down to a local/district level ons.gov.uk/peoplepopulati…
2/ This piece—developed by my colleagues @Annaekhoo (#DataJournalism) and @SamCtrl (#DataViz) from analysis by Amy Boyson (@ONS historical)—has been an opportunity to test some of the techniques we’re hoping to use to explore 100 years of change up to the most recent @Census2021
3/ In particular we've been exploring ways to use historical @OrdnanceSurvey maps painstakingly digitised by @natlibscotmaps as a background for the historical datasets. We hope this #steampunk-esque retro-innovation helps to bring the past to life...
1/ Today we published this first of two interactive #scrollytelling pieces focused on economic inequality in the UK, based on measures of income and productivity for each local area. Check it out here... ons.gov.uk/visualisations…
2/ As you'd expect, the analysis found notable economic disparities between southern England and the rest of the UK (the blue map shows relative income, the pink shows relative productivity)... But there were also other notable findings
3/ Importantly, the analysis found some interesting patterns once the two economic measures were overlaid as a #bivariate map, including disparities between cities and their surrounding rural areas (the scatter plot top-right explains the colours)
2/ Looking at the history of the region in this way helps us to put today's events in context. Eg. in "mixed cities" like #Jaffa, #Haifa or #Lydd, where many #Palestinians were forcibly displaced in 1948, and those that remained became an isolated minority today.visualizingpalestine.org/lydda/
1/ Nerdy thread... I recently put together this tool for exploring @ONS statistical geographies & administrative regions for England & Wales. It's one of various prototypes that we're working on in the #DataVis team in thinking how to visualise @Census2021bothness.github.io/geo-explorer/
2/ Since joining @ONS a few months ago, I've been trying to make sense of the MANY geographies are used to report data across the UK, from neighbourhood level all the way up to national level, and to be honest it's been a challenge. Here's a list from the 2011 Census...
3/ The smallest "statistical building block" for census data in England & Wales is an Output Area, covering around 100 households. These areas are so small that there are over 180,000 of them, and they don't even have names, only 9-digit codes like E00080085
2/ All of the maps are in the public domain (expired copyright), sourced from archives including the David Rumsey map collection, the Israeli and Australian national libraries. The maps are all scanned at resolutions of at least 300dpi. Here's an example of the detail level...
3/ We also just added a new split-screen mode to #PalOpenMaps, so that you can instantly compare the various historic map layers to present day satellite maps and #OpenStreetMap road overlays palopenmaps.org
