Census Transformation Programme

last person joined: 7 days ago 

The aim of the Census Transformation Programme is to make the best use of all available data in England and Wales to enhance the provision of population statistics. It will provide a predominately online census in 2021, it will seek to increase the use of administrative data to enhance population statistics, and it will form plans for the provision of population statistics after 2021.

The three major strands of concurrent work in the Census Transformation Programme are:
1. An online census
The programme will provide a predominantly online census of all households and communal establishments in England and Wales in 2021 with special care taken to support those who are unable to complete the census online. This will look at how we run the 2021 Census data collection operation and its coverage survey (including the address register, field force, online/paper data collection, public support and enumeration of communal establishments).
2. Administrative data
The programme will increase the use of administrative data and surveys in order to enhance the statistics from the 2021 Census and improve annual statistics between censuses. This will look at how we integrate census and administrative and survey data to provide and disseminate census outputs.
3. Plans beyond 2021
The programme will decide how we provide these statistics after the 2021 Census.

This community is for all posts relating to the census and the wider remit of the Census Transformation Programme.

1.  Method of Travel to work data

Posted 14-02-2013 12:51
Most of you will have seen ONS' published method of Travel to Work table QS701. When we looked at it, we were puzzled that the apparent proportion of people working at home had fallen between 2001 and 2011  which wasn't what we would have expected.
ONS has just released a paper analysing Travel to Work data, which says that QS701 isn't completely compatible with KS015 from the 2001 Census in its treatment of people who work at home, but they have a released an additional table CT0015 which gives an alternative take on the data and is compatible with 2001 Census data.

However, CT0015 only has data at district level and I'm informed that ONS are not planning to release this table for smaller geographies. This would mean that we could obtain compatible data between 2001 and 2011 at district level, but 2011 district and small area figures wouldn't be compatible, OR we could have figures that are compatible beween districts and small areas at 2011, but which aren't comparable with 2001 data.

Surely this is unsatisfactory and reduces the usefulness of the data?

Hi Tim,

Apologies for time taken for response, but here it is now:

The data on travel to work are not directly comparable between 2001 and 2011, because of a change to how they were processed.

In 2001, if a respondent recorded that their Workplace Address was "at home", it was assumed that they did not travel for work, and they were also recorded as working at home in the Travel data.

However, in 2011, this assumption has not been made. Therefore, any respondent who works at home, but also travels (e.g. a mobile hairdresser) is recorded as "Working at home" in data or Workplace (which has not yet been published) but as "Driving" (or whichever mode of travel they recorded) in the Travel data. This is more relevant to transport planners and other users.

As we are aware that some users will also want to compare these data with the 2001 Census, we published an additional table on 13th February, to present the 2011 data on the 2001 basis (so mobile hairdressers will count at working at home) at a Local Authority level. As these data are less accurate than those in the Quick Statistics table, we have no plans to produce this table at lower levels of geography as a standard product. However, those data could be commissioned, subject to Statistical Disclosure Control.

When we produce "flow data" outputs, respondents who have a method of travel to work but no destination (e.g. the mobile hairdressers) will not be included, as there is no flow that can be shown. These data will be on a comparable basis to outputs from the 2001 Census.

I'm still a little confused about the travel to work data. Let's suppose in Census 2011 someone indicates in Q41 that they work at or mainly from home but in Q40 gives a workplace address other than their home. In
2001  they would not be considered as travelling to work but in 2011 they would . But you have no way of knowing how they travel, when they do so,  because Q41 allows  for only one answer and they have selected the first (home) option. So are you assuming that the distribution of method  of travel for such persons follows that of those who don't work at or mainly from home and , if so, how do you justify that assumption?

Also, the assertion that Q41 in 2011 is "fully comparable" with the corresponding question in 2001 seems false.

I've just received a commissioned table of Travel to Work for wards and higher geographies in England and Wales produced on the same same basis as 2001. The table CT0045, is identical to CT0015 for districts and higher geographies. It can be found here: table CT0045
