Vacancy Flow Data
Could someone explain why the sum flow and change between summed periods analyses are available for the vacancies by occupation variable but not the industry one?

|Not an answer, but do recall that the JCP vacancies are not quality-assured as National Statistics. There are reasons for this ... partly due to prior changes in the way JCP has marketed its vacancy service to employers and managed the results.
The industry analysis carries an even larger cautionary note - as agency vacancies are listed under the employment agency industry rather than the industry in which the work placement is (logical, as the agency holds the P45). ONS vacancy survey not available locally measures vacancies from ultimate user industry.
If someone can explain to me what the use of the industry classification is, other than we've always done it that way, it might be interesting (N.B. I've over 30 years experience in the field).

|The vacancy series was suspended for several years prior to their reintroduction in June 2005. As Paul notes, ONS were still concerned about the data quality and included a warning message with the rerelease stating that figures are not fully comparable over time.
A particular factor with the industry data was the change in from Sic92 to Sic03 in May 2005. Back in June 2005, ONS felt that we should not provide facilities such as sumdata which could allow users to create figures for periods which spanned the change so merged figures from the two classifications.
As we are several years on from 2005, we could ask ONS to review the original decision. However, as the industry dataset tends to be little used in comparison to the occupation one for the reasons Paul mentions, it is unlikely we would prioritise the work in the near future.

|On a similar but related theme, can you please clarify that "notified vacancies" variable in the "vacancies - summary analysis (Apr 2004 to Oct 2009)" report is measuring the stock of vacancies at a point or the flow during the month.

|notified is all notified between the count dates. think of them more as in-flows|

|Sorry, only just picked up on the replies to my original query. I accept it's not a priority, but I produce monthly figures on vacancies by industry (it's another piece in the jigsaw when assessing economic trends) and would welcome you asking ONS to review the decision not to allow sumdata queries.|
