Deafness affects many social interactions. The impact of deafness depends on several factors, e.g., the type of social environment in terms of the particular Deaf community a person lives in. The authors recorded the birthrate and the proportions of married and divorced people among deaf people in two Swedish counties: Narke, which had a strong Deaf community, and Varmland, whose Deaf community was weak. In both counties, the authors found that deafness was associated with low marriage rates and low birthrates. Further, in Narke, 99% of the people in the sample were married to another deaf person; only 10% were in Varmland. In Narke, the divorce rate among deaf people was about the same as that of the reference population (i.e., the county's marriage-age population). In Varmland, deaf people had a relatively low divorce rate. The findings are discussed from medical and social perspectives.
