The purpose of this research is to identify the differences in motivation to move into +40 cohousing, participation in common activities, evaluation of physical environment design, and life satisfaction of Swedish +40 cohousing residents between single and cohabitant households as well as female single households and other types. The data of 127 respondents from 4 of ‘+40 cohousing’ communities used for this research are the subset of data (Choi & Paulsson, 2011) nationwide surveyed from 12 cohousing communities in Sweden. The results showed that there were some notable differences in housing characteristics, motivation to move in, participating in common activities, and evaluation of physical environment design. However, there was no difference in life satisfaction. Single households were more likely than cohabitants to be female and aged and tended to reside longer in a smaller dwelling, the aspect which female single households shared. Also, single households were more motivated to move in by personal reasons but less so by housing management reasons. Female single household had similar reasons to move in, except having more items related to security reasons. Single households were more likely than cohabitants not only to frequently participate in common activities such as common exercise/gymnastics/walking and common gardening, but also to highly evaluate common facilities such as exercise room/or similar and bath/sauna. Similar to single households, female single households were more likely than other households to frequently participate in exercise/gymnastics/walking activities and to highly evaluate various common facilities. The level of life satisfaction was not statistically different in both pair of the groups. The result of this research implies that the distinct differences of +40 cohousing found in previous research with respect to general characteristics of residents and dwelling, motivation to move into +40 cohousing, participation in common activities, evaluation of physical environment design might reflect characteristics of cohousing living of single households and more or less female single households. However, their life satisfaction remained high regardless of living situation and gender. Understanding the differences between the two pairs of groups may contribute to understanding and revitalizing the living in +40 cohousing community.
