2011 Census Flow data in SASPAC

04/02/2016

All 2011 Origin/Destination Census flow tables have been released by ONS and are available through a small software update.

In total there are 147 ‘Public’ and ‘Safeguarded’ flow tables available for users to access through SASPAC on their desktop.

Public SASPAC System files are downloadable from here.

Safeguarded System files may be downloaded from the UK Data Service website but require users’ to agree to additional t&cs via a ‘Safeguarded licence’ provided by the UK Data Archive  – see here (.pdf) for guidance on how to do this.

A release note with update instructions can be found here, whilst the latest SASPAC System files can be found here. Please contact the helpdesk if you have any issues with this update.


2011 Census Evaluation Report

26/02/2015

In January 2015 ONS held a 2011 Census Outputs Evaluation workshop at City Hall, London. The meeting was an opportunity for reprsentatives from local authorities, business, academic and third sector Census users to feedback their experiences from 2011 to the Census Offices. Each sector presented their opinion of what ‘went well’ and what lessons need to be learnt for 2021. All the slides and a report (.pdf) from the day have now been published on the ONS website.

Callum Foster also shared some of ONS’ early thoughts on the potential data delivery channels we can expect following 2021:

There is a plan to publish around 200 tables via this route between January-March next year. Remember there are additional terms and conditions regarding the use of these statistics and we will be providing more details in a blog post soon.

A release note with update instructions can be found here, whilst the relevant SASPAC System files for E&W can be found here and the Scottish data here.


New 2011 Census Datazones for Scotland now in SASPAC

21/11/2014

NRS have recently published the new 2011 Census Data zones and Intermediate zones areas – previously Census data has been published for 2001 DZ/IZ on a best-fit basis. The 2011 lookup tables are available to download from the NRS websiteDownload SASPAC Installer

These zones have been created by aggregating 2011 Census Output Areas (on an exact-fit basis). The SASPAC team have created Key Statistics, Quick Statistics and Local Characteristic datasets for these new zones and the System files are now available for download from our data page or a direct link to the System files is here (743MB .zip).

Data has been generated using SASPAC’s rezoning facility – remember you can create your own custom areas and all the steps are explained in Module 4b. When viewing these new geographies in SASPAC the zones will appear as flat trees (i.e not grouped by LAs), we are currently updating the software to incorporate these hierarchies and a software release will be available shortly.


Incorrect 2011 Workplace flows

19/11/2014

Following users’ concerns over unusual flows in the 2011 Workplace tables released at the end of July (i.e. flows between LAs with large distances between them), ONS have investigated the issue and discovered errors in the coded workplace addresses. There is no plan to re-release these tables but a quality report (pdf) is now available which explains the issues and areas effected.


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.


Training videos

We have recently developed more training videos. Please take a look on our page to view these great step-by-step videos now currently available.
The most recent videos added are:

Module 8
Part A,
Part B and
Part C

This module shows you how to work with origin-destination dataset sets including filtering the data, rezoning to asymmetric zones and outputting the data into either an Excel pivot table or into Mapshore.
