India - Housing Condition Survey, July - December 2002, NSS 58th Round

Principal earner of the household is that person among the household members who had the highest earnings during the 365 days preceding the date of survey from any type of activity, economic or non-economic. One way actual distance (in kilometres and in whole numbers rounded to the nearest integer) from residence to the place of work normally travelled by the principal earner of the household will be recorded here. The reference period for this item is the last 365 days. For persons, whose place of work is not fixed, e.g. hawkers, casual workers, mobile trade, etc., the distance normally travelled from residence to the farthest point of his/her area of operation may be recorded. If the distance to the place of work from residence is less than 0.5 km., '0' may be recorded.
