A survey of baby booms and busts in 20th century Spain

Abstract

BACKGROUNDThis paper presents a new source of microdata on women's reproductive life in 20 th century Spain, the Baby Boom and Bust Survey (BBBS). While certain countries have other sources of microdata such as censuses or specific fertility surveys that have been useful in shedding light on aspects of reproduction, few provide the longitudinal, integrated, and nuanced perspective afforded by this survey. The Baby Boom and Bust Survey includes women's reproductive histories for the period prior to the baby boom, the baby boom itself, and the early stages of the baby bust. OBJECTIVEThe purpose of this paper is to describe this data source, its content, its methodological underpinnings, and the way the fieldwork was carried out. METHODSThe survey was administered to a total of 1,021 women above 60 years of age residing in Spain in 2012. A random sample was used and access to informants was secured via the Padrón Continuo (the continuously updated local population register of Spain). The distribution by characteristics closely fits the sample frame.
