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:

Flow data & SASPAC

28/01/2015

2011 Census Safeguarded flow datasets have begun to be released by ONS and are now available in SASPAC. Currently 15 tables have been published via the UK Data Service, with further tables expected throughout Feb/March. Tables currently available include data on:

  • Output Area to Workplace zone flow counts
  • MSOA/Intermediate zone worker flows by age, sex and mode of travel
  • Output Area to Output Area migrant flow counts
  • ward to ward migrants flows by age groups and sex

A list of tables currently published is here (.xls).

Flow datasets are available under three levels of licence: Public, Safeguarded and Secure:

  1. Public – open and accessible like any other Census data (downloadable in SASPAC from here)
  2. Safeguarded – available to public sector and academic users to download in a SASPAC format from the UK Data Service – requires users to sign up to additional t&cs.
  3. Secure – available within the ONS Virtual Microdata Laboratory (VML) to Approved Researchers for specific projects – SASPAC is available in this environment.

Instructions on how to access the SASPAC data via these channels is explained in the attached guidance note (.pdf) along with important information regarding the End User Licence. Importantly, and unlike the majority of Census outputs, this licence has two specific conditions:

  1. data is licensed on an individual basis (not an organisation), so users are required to ensure only licensed individuals can access the Safeguarded data files.
  2. Users are also required to suppress any counts lower then 3 or replace 1s or 2s with 0 or 3.

SASPAC v9.93 is required to access these tables and more details on this dataset are available on our dedicated flow data page.

To support access to these datasets we are running a series of training courses specialising in flow data – a programme for the day is here (.pdf) and dates here. Flow data training materials and videos are also available.


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.


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

26/09/2014

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.
