IA National Data Service – Census 2021 first results

The first results of Census 2021 were added to the National Data Service on 4th July 2022 and are now available for viewing.

This brand new set of around 140 indicators can be found in the the Population theme, under a Census 2021 subtheme. This dataset combines the first release results for 2021 – available at local authority, region and country level for England and Wales – with the closest equivalent data selected from NOMIS for 2011, 2001 and 1991 to show change over time in the headline data. The population estimates are broken down by sex, broad age group and 5-year age groups.

Note that there may be some differences to the basis on how the values were generated. Note also that this first release data for 2021 gives figures rounded to the nearest 100 – later release will be unrounded and can be expected to show some differences to these figures.

For customers with a managed Data Observatory website, the data are displayed in the following places:

1) Population reports for top and lower tier local authorities (updated 7th July 2022)

NDS report with Census 2021 data

2) Population Map Explorer (updated 4th July 2022)

Map Explorer with Census 2021 data

3) Data Explorer (updated 4th July 2022)

Data Explorer with Census 2021 data

We will add further data from Census 2021 to the National Data Service once these have been released. You can read the release plans from ONS for the data here.

How to embed InstantAtlas apps into your website

The purpose of this post is to provide the necessary information for embedding InstantAtlas apps into a website. Colour is used to explain the code below – if you have difficulty distinguishing the colours used please contact support@instantatlas.com and we will find an alternative. The actual creation of the apps in the first place is not covered in this post.

Data Explorer

InstantAtlas Data explorer apps connect directly to an InstantAtlas Data Catalog in ArcGIS Online and allow your web site users to browse and download data and create graphics for documents and presentations.

Add this code to a web page to embed a data explorer app.


<link href="https://hub.instantatlas.com/data-catalog-explorer/static/css/main.css" rel="stylesheet">
<div id="root"></div>
<script src="https://hub.instantatlas.com/data-catalog-explorer/static/js/main.js"></script>
<script>window.dataCatalogExplorer.launch({ "appid": "e3d83edc76bd45548ddd0e2ee4fe4bdf", "container": "root" })</script>‎

e3d83edc76bd45548ddd0e2ee4fe4bdf – this is the app ID (from ArcGIS Online) of the data explorer app you wish to embed.

An example of embedding a data explorer app can be seen on this page of the Suffolk Observatory.

Map Explorer

Map Explorer apps are simple-to-use apps that that allows a user to select from a pre-defined set of indicators from an InstantAtlas Data Catalog and visualize them as thematic maps.


<div id="ia-map-panel" style="width: 100%; min-height: 500px; height: calc(100vh - 300px);">
<script src="https://hub.instantatlas.com/map-explorer/embed?c=ia-map-panel&appid=917b1891e5934d6baeeff23cdb0e9f38"></script>
</div>

917b1891e5934d6baeeff23cdb0e9f38 – this is the app ID (from ArcGIS Online) of the map explorer app you wish to embed.

Custom Area Reporter

The Custom Area Reporter is an app that allows users to make a custom selection of areas to be viewed in an aggregated or disaggregated form in a report published using Report Builder for ArcGIS. Users select areas from a map using a range of selection tools. Once the areas have been selected, the user can choose from a list of reports – this list is defined in the app configuration.

Add this code to a web page to embed a custom area reporter app.


<link href="https://www.reports.esriuk.com/custom-area-reporter/static/css/car.css" rel="stylesheet">
<div id="car-container" style="width: 100%; height: 500px; border: 1px solid #ccc; position: relative;"></div>
<script src="https://www.reports.esriuk.com/custom-area-reporter/static/js/car.js"></script>
<script defer="defer">window.customAreaReporter.launch({ appid: '1a451d1bbe3544849585ab2745c25f5d', container: 'car-container' });</script>

1a451d1bbe3544849585ab2745c25f5d – this is the app ID (from ArcGIS Online) of the custom area reporter app you wish to embed. The code above contains some styling of the container for the app that you can obviously change if you wish e.g. width, height, border. An example of embedding a custom area reporter app can be seen on this page of the Suffolk Observatory.

Reports

The embedding of reports created using Report Builder for ArcGIS is covered here.
