20.2. Duration of residence in this city/village (in years), Column 15
Fill this column only for people who have changed their place of residence since October 1996 (code 1 in column 14), and leave it blank for others. For this purpose, ask them the duration of their residence in this city or village and write down the result in the form of a two digit number in years. For instance, for someone who has been living here for 4 years and 11 months, write "04" in this column. For those who haven't been living there for more than one year, write "--".
Since you ask this question only from people who have been living in this city/village from October 1996 or after, the number you write in this column cannot be bigger than 10.
Remember that the duration of residence in this city/village is the time during which they have started living here constantly through the enumeration time.
