In parallel with the recent trend towards conducting ever more surveys, there has also been a decline in response rates, making it harder to obtain the desired number of completed interviews for these surveys. Incentives used in surveys, with the aim of increasing the response rates are manifold, varying from sending letters in advance and an increasing the number of reminder calls to pre-interview payments, cash incentives, charitable donations, and the chance to win lottery prizes. This book examines the impact of incentives and methods used to increase survey response rates.
