Flow data

20/10/2014

Today ONS updated the timetable for the publication of the 2011 Census flow data. These datasets relate to:

  • Travel to Work (or study in Scotland)
  • Migration
  • Second Residences
  • Student migration

The next data to be published will be four Safeguarded migration tables including:

  • OA to OA/country flow (counts)
  • ward to ward flows by sex and age 

These are expected to be available later this month, with the Secure tables coming in November and safeguarded tables in December.

All Safeguarded tables will be available in SASPAC and users will be able to download the System Files from the UKDS website directly (having registered and accepted the T&Cs).

All Secure flow tables will only be accessible to approved researchers via the ONS secure VML (Virtual Microdata Laboratory). SASPAC will be available in the VML to allow our users to integrate these datatsets.

More details on the flow data, including table layouts, can be found on the ONS website and details of SASPAC’s specialist OD training courses here.


SASPAC Training – OD Flow data

03/09/2014

The SASPAC team have developed a new training course to support users’ access to the Origin/Destination flow data that has begun to be released by the Census Offices. This dataset includes details of usual residents:

  • Travel to Work (or study in Scotland)
  • Migration
  • Second Residences
  • Student migration

SASPAC provides users with the tools to access, manipulate and analyse this complex dataset. The course is designed for current users of the software interested in using the application to understand the flow data – a course outline can be seen here. The first course is scheduled for Wednesday 17th September at City Hall and more dates can be found on our booking page.

NB: In order register on this course you must have been on the Introduction to SASPAC course or be a long-time user of the software.

The first set of Public Flow data tables were released at the end of July and further releases (Safeguarded & Secure) are scheduled for the end of September and then again in November. All of these tables will be accessible through SASPAC either on users’ desktops (following the completion of the necessary licence) or the Census Offices physical sites via the Virtual Microdata Laboratory (VML).

Please contact info@saspac.org if you are interested in securing a place. We will allocate places on a first-come-first-served basis.

2011 Census: Workday Population Statistics for Middle Layer Super Output Areas (MSOAs) and Output Areas in England and Wales (Part 2)

A production error was discovered in table WD1101EW. The workday populations for eight Output Areas were incorrect – with some cells containing inconsistent counts for age or sex categories that did not sum to the total population. The eight Output Areas affected were: E00015045, E00023289, E00049002, E00159643, E00172150, E00170915, E00172167, E00174876 (across LB of Kingston and Wandsworth, Warwick, and Coventry) . Correcting the figures for these areas has resulted in changes to the figures for five Middle Layer Super Output Areas (MSOAs).

The SASPAC team have corrected these System files and updated the Workday tables for MSOAs in England and OA in West Midlands and London. The new System files may be downloaded from here.


SASPAC & Census flow data

24/07/2014

The Data

The Census Offices are preparing to begin publishing the 2011 Census flow data, these tables will include 4 datasets:

  1. Special Workplace statistics (SWS) – travel from usual residence to workplace (or place of study in Scotland)
  2. Special Migration statistics (SMS) – address 1 year prior to census day
  3. Special Student statistics (SSS) – student migration
  4. Special Residence statistics (SRS) – location of second residence

For all 4 datasets a set of England & Welsh and UK tables will exist.

How will I be able to access the data?

ONS have developed 3 levels of licence to access the data:

Public: openly available anyone and accessible to SASPAC users like any other Census data. These will include a small number of simple tables published for large geographic areas such as local authorities/MSOAs.

Safeguarded: available to researchers under a separate licence agreement. SASPAC are currently working closely with ONS and the UK Data Service to enable these tables to be available to our users on the day of publication (at this stage it is expected that the Safeguarded data will require users to agree to individual terms and conditions which will allow them to download the data in a SASPAC format. Data will then be accessible like any other dataset in SASPAC on their desktop).

These are slightly more detailed tables for larger geographies or simple tables for smaller geographies such as OA/WPZ/ward.

Secure: accessible via the ONS Virtual Microdata Laboratory (VML) held at Titchfield, Southampton. These will include the most detailed cross tabulations, available for the smallest Census geographies and data will only be released to users following ONS approval. SASPAC will be available to access these tables in the VML.

A new VML is currently under development by ONS and expected to be available at other sites across the E&W towards the end of the year.

When will the data be published?

Public tables: 25 July – 9 for E&W (3 SWS/6 SRS)  and 11 for UK* (6 SMS/3 SWS/2 SRS). These are ‘priority tables’ and more tables are planned from November 2014.

Safeguarded tables: August (date TBC) – 4 E&W (SMS) and 10 UK* (4 SMS /6 SWS). These are ‘priority tables’ and more tables are planned from November 2014.

Secure tables: details and date TBC

* Initially UK tables with only include England, Wales and NI flows. This is because issue has been identified with the Scottish data by NRS.

How to access the data?

Public – available to SASPAC users in the usual manner; users will be informed when system files are available for download.

Safeguarded – available to researchers under a separate licence agreement. SASPAC are currently working closely with ONS and the UK Data Service to enable these tables to be available to our users on the day of publication (at this stage it is expected that the Safeguarded data will require users to agree to individual terms and conditions which will allow them to download the data in a SASPAC format. Data will then be accessible like any other dataset in SASPAC on their desktop).

These are slightly more detailed tables for larger geographies or simple tables for smaller geographies such as OA/WPZ/ward.

Secure: available through SASPAC via the ONS VML

What SASPAC support will be available?

The SASPAC team are currently preparing/updating training materials to support users’ access to the 2011 flow datasets. We expect to make half-day training sessions available to users and we will post dates on our website shortly. In the meantime, if you wish to get familiar with the 2001 flow data, the data may be downloaded from our website along with supporting 2001 training materials.
