Descrizione

Telephone surveys are a cheap and quick method of collecting survey data. When sampling the general population, Telephone Directories may be used as sampling frames. When these Directories are incomplete, non-coverage errors may occur and survey data may be biased. In Italy, 50% of individuals are excluded from the Telephone Directories. Using data from the 2012 Multipurpose survey, this paper explores the relationship between telephone under-coverage and data quality; in particular, it assesses the impact of telephone under-coverage on bias for a set of 32 survey items and explores the effectiveness of post-stratification strategies. We find that the exclusions of cell-only and unlisted individuals is a major source of bias and post-stratification strategies currently in place are ineffective in removing the bias. We also find that the nature of the relationship between under-coverage and bias is complicated: it varies between and within topics.
