Flow Data Information System
2001 Census: Special Workplace Statistics (Level 3)
Contains journey-to-work flows within and between output
areas in England and Wales. Note: OA-level workplace
data have not been produced for residences in Northern Ireland. The Special
Travel Statistics (STS) contain journey-to-work information for residences in
Scotland.
Users can choose from 36 counts in 1 table. This set of 36
counts includes a number of totals and sub-totals; the number of
interior cells which form the basis of these sub-totals is
22.
All the 2001 SWS data have been derived from the 100% sample and
include imputed households. Where workplace locations were unknown, these
were also imputed.
Disclosure control
Data associated with residences in England and Wales (i.e. all of this
dataset) have been modifed via a process known as Small Cell
Adjustment Methodology (SCAM). The SCAM process is a disclosure control
mechanism. For all tables process using SCAM, interior cells with a 'small'
value have been adjusted. 'Small' values are understood to be in the range
0-3. Cells with an initial value of 1 have been rounded to either 0 or 3,
with 0 being the more likely result. Cells with an initial value of 3 have
also been rounded to either 0 or 3, but with 3 being the more likely result.
Cells with initial values of either 0 or 3 have retained these values although
in each case it is impossible to distinguish between rounded values and
'genuine' 0s or 3s. All sub-totals and totals have been re-calculated from
the rounded cells.
There are three noticeable effects of SCAM
- Within-table modification. For the majority of
outputs, it will be apparent that a large proportion of cells within any
table are either 0 or 3, and that sub-totals and totals within the table are
multiples of 3.
- Between-table variation. SWS Levels 1 and 2 contain
several output tables, with the result that a number of values (e.g. 'total
migrants') can be found in more than one table. Due to SCAM, these values
may not be consistent between tables.
- Between-level variation. The three spatial levels for
which the SWS are available were independently subject to SCAM. Thus, if a
particular value (e.g. 'total migrants') is calculated by aggregating from
one spatial level to a higher one, and compared to the value found in
the SWS data set for that higher level, those values are unlikely to be consistent.
Users are advised to ensure that data they use has been calculated by
summing the minimum number of base values.
