Lifestyles, living conditions and employment in uncertain times. Population and employment patterns in Belgium during the 'long, drawn-out nineteenth century', Eric VanhauteIn recent decades, historic-demographic research has asked new questions, used new sources and experimented with new methods. Yet these innovative trends which have produced a wealth of findings, have failed to revive the debate about broad, overarching patterns and models, which is still dominated by all-encompassing modernization concepts such as the 'demographic transition'. This article argues for a renewed, unbiased dialogue between micro and macro approaches and formulates some ideas about bridging the gap between the rich but splintered domain of demographic micro research and historicising models of social transitions. A survey is presented on the accumulated knowledge about important transitions in demographic trends witnessedin 19th century Belgium: Population growth, birth rates, death rates, nuptuals and fertility, conditions in which people lived together and family formations, as well as housing and employment. These processes are subsequently interpreted within the context of the structural transition to an 'extensive' 19th century and an 'intensive' 20th century social model, respectively.
