Initially, the ONS aim to make the topic summary datasets available down to the smallest geography; Output Area (OA) level. As soon as is practical, they plan to provide these datasets for other geographies, using the OA best-fit approach.

All appropriate census data will be automatically added to the Data Observatory.

Due to the volume of census data being released, there may be some short delay between the data being published and being added to the data observatory. However, those requiring immediate access to the data will still be able to do so via the ONS website.

As each of the eight Topic Summaries are released, the Insight Team will produce eight corresponding infographics which will be published via the Data Observatory.

These will graphically summarise the high-level findings, under that topic, for Hull and compare to regional and / or national figures. They will not include any analysis or narrative; but serve to provide an ‘at-a-glance’ overview of the latest socio-demographic characteristics.

Phase 1.2: Area Profiles (October 2022 – January 2023)

Alongside the release of topic summaries, data will be made available through area profiles, created from the univariate topic summary data.

These will allow the user to view key statistics from across different topics for a particular geographic area and compare local statistics for an area against national statistics.

Area profiles will include data on population, identity, health, housing, education and work.

The ONS aim to make area profiles available for a range of area types over time, starting initially with local authorities and wards. These area profiles are similar in concept to those available on the NOMIS website.

Phase 2: Multivariate Data (Winter 2022 to Early 2023

In Phase 2, the ONS will release multivariate data based on the usual resident population; allowing users to combine multiple variables and explore relationships between the data.

Users will be able to view and download standardised multivariate datasets or create their own, by selecting or changing different combinations of variables, classifications and geographies.

As multivariate data is made available in Phase 2, the Insight Team will produce a series of detailed census analyses based on data specific to Hull. The aim is that these will complement the published data; providing additional insight and cohesive narrative, helping users to better understand the needs of Hull residents, and informing decisions on future policy and services. These will be published via the Data Observatory.

The subjects of these analyses will be informed by the census results themselves, but we propose they include the following, to reflect proposed ONS UK level analyses:

1. Ageing
2. Demography
3. Education
4. Equalities
5. Ethnicity, nationality, language and religion
6. Health, disability and care
7. Housing
8. International migration
9. Labour market
10. Sexual orientation and gender identity
11. Travel to work
12. Veterans

Each of these analysis proposals are subject to review following a period of user feedback, the exploration of published census data and other dependencies. Therefore further details regarding both content and publication timescales will be provided as census data is released.

The Insight Team will only be able to support with bespoke census data requests / analyses after these detailed ‘Hull focussed’ analyses have been produced. However, individuals will have self-service access to census data via both the Office for National Statistics website and the Data Observatory.

Phase 3: Alternative Population Bases (From Spring 2023)

Data in Phase 3 will focus on:

• Alternative population bases: These are different geographical locations where individuals could have been counted e.g. workplace, workday, out-of-term and short-term populations.
• Small populations: These are groups which are defined by their cultural background, including characteristics such as ethnic group, country of birth, religion and national identity e.g. gypsy and traveller.
• Origin-destination data: This describes the movement of people from one location to another e.g. migration flow, workplace flow / commuting, student flow.
• Microdata: Samples of anonymised records for individuals and households which include a selection of associated census characteristics.
