1. Auxiliary data for the LFS
Sven Egmose,
Statistics Denmark

2. Drawing sample Register on the population
Extended with other data from registers
7 strata for two reasons
Oversampling of groups of special interest
Different response rates

3. Response rates 2018,Q3 Total 58,0 Men 56.7 Women 59.3 15-24 55.8
Without vocational educ. 52.9
Vocational education 58.6
Further education 61.3

4. Consequenses of no auxiliary data
Overestimation of women
Heavy overestimation of the elderly
Heavy underestimation of persons without a vocational education
(52.9 – 58.0) / 58.0 = 12.2 Percent

5. The enumeration process
Stratas because of
Different response rates
Different attachment to the labour market

6. Stratas for enumeration
Age
Sex
Address
Level of education
Socioeconomic status
Number of children
Citizenship
Unemployment benefit
Gross income

7. Status and response rates
Empl Un- Outside Response
empl lab. force rate
Without voc
Vocational
Further educ
Total

8. Without auxiliary data
Overestimation of employment by 26,000
~ 1 Percent
Underestimation of employment among persons with no vocational education by 50,000
~ close to 10 Percent!

9. Data on level of education
High quality statistical register
Based on yearly reports on individuals from the educational institutions
Register data used directly
Except for actual educations because of delay
Actual educations from interviews
Lower response burden
Higher data quality
Avoid problems on recalling exact education

10. Activity code Variable on establishments But here on job
Difficult to obtain
A respondent knows what he is doing but does he know what is the activity of ‘his’ establishment?
Example: salesman working for manufacturing
Precise description needed in order to code.

11. One alternative solution
Asking for name and address of the establishment
Matching with the SBR
Precise name and address needed
Problems on recalling
Google Maps used as a tool
But still some problems

12. New strategy Using the Register based statistics on empl. (RSE)
6 Months delay for the RSE
RSE activity code used for LFS employees without new job within six months
Else: Name and address of establishment
Else: coding based on respondents description
Result of new strategy:
Better quality and lower response burden
