Three 'Phase 1' variables of particular relevance to demography and population census statistics
The Working Group is kindly asked to provide its comments about the three following “Phase 1” variables presented in annex:

Proposed date for sending by , by 18 May, to
Or comments at the Working Group on May.

5. Variable 1 name: Sex

characteristics that define a person to be either 'Male' or 'Female'
Data should be categorised into ‘Male’ and 'Female', and might in
addition contain the category 'Unknown'.

Total 
Male
Female
Unknown

6. Guidelines
In case the biological sex of a person is not known, the information should be replaced by either the administrative sex (administrative data) or the self-declared sex (survey data).
In the absence of this information, one of the following shall be done (in order of preference):
1. Information on the variable should be imputed into the data record by attributing the most plausible value;
2. The record is disregarded for all categories except the total and the variable has to be adjusted using an appropriate methodology. 

7. Variable 2 Date of birth and Age
‘Date of birth' describes the calendar date on which a person was born. The variable 'Date of birth' is to be used for the transmission of micro data.
‘Age’ is the interval of time between the date of birth and the date of reference. The variable 'Age' is to be used for the transmission and dissemination of tabular data.
Measurement: 'Age in completed years' or ’Age reached at the end of the reference year'   
Category concepts of the variable 'Date of birth' : day, month and year.
Category concepts of the variable 'Age': define the time span expressed in a number of years or a time span covering more than one year (e.g. 5-year age groups).

Category 'Unknown' in the concept system for 'Age' shall not be used for transmitted data.
Where this information is absent, one of the following shall be done in order of preference:
1. Information on the variable should be imputed into the data record by attributing the most plausible value;
2. The record is disregarded for all categories except the total and the variable has to be adjusted using appropriate methodology.

12. Variable 3 Arrival / Duration of stay in the country of residence
The ‘Date of arrival in the country of residence' describes the calendar date on which a person has most recently established usual residence in the reporting country. The variable 'Date of arrival in the country of residence' is to be used for the transmission of microdata.
The ‘Year of arrival in the country of residence' describes the calendar year during which a person has most recently established usual residence in the reporting country. The variable ‘Year of arrival in the country of residence' can be used for the transmission and dissemination of tabular data.
The variable 'Duration of stay in the county of residence' shall describe the time span between the point in time when a person most recently established usual residence in the reporting country and the reference date.
The variable 'Duration of stay in the county of residence' can be used for the transmission and dissemination of tabular data.

13. 'Date of arrival in the country of residence' include the day (specified in two digits), month (specified in two digits) and year (specified in four digits) when a person most recently established usual residence in the country. It also includes the category 'never resided abroad'.
 'Year of arrival in the country of residence' describe the calendar year (or group of subsequent calendar years, respectively) in which a person most recently established usual residence in the country.
 'Duration of stay in the country of residence' describe the time span between the date of arrival in the country of residence and the date of reference.

14. Options for transmission
'Date of arrival in the country of residence' describes the options to be used for the transmission of microdata containing information on that variable.
For any person who has never resided abroad, the categories 'year', 'month' and 'day' do not apply.
Options for transmitting 'Date of arrival in the country of residence' 1 2 3

For any transmitted data the variables 'Year of arrival in the country of residence' and 'Duration of stay in the country of residence' have to be derived from the variable 'Date of arrival in the country of residence'.
