it is important to keep in mind however the limitations of using survey data for such an analysis first household surveys typically provide reliable information only on the amount of different types of benefits received by an individual or household over the period of a year the measured share of youth who receive benefits at any time during the year will generally not be a good estimate of the benefit receipt rate at a certain point in time ie in a specific month unless if benefits are typically paid for periods of close to a year for this reason receipt rates estimated using annual survey data may be different from those obtained from administrative records where shorter spells of benefit receipt can often be observed for a discussion see immervoll jenkins and konigs
