Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
Write down the present MARITAL STATUS of each person. Make sure that only those people who have never been married are classified as such, not those who are presently not married, but have been married in the past. For instance, individuals whose spouse has died, or who are divorced or separated should be listed explicitly as such using code 3 or 4 respectively.
