The sociology of the family examines the family as an institution and a unit of socialization. This unit of socialization is identified through various sociological perspectives; particularly with regards to the relationship between the nuclear family and industrial capitalism, and the different gender roles and concepts of childhood which arose with it. Family is said to be an essential for a healthy mind.
Sociological studies of the family look at:
Examples of specific issues looked at include:
Research methods in the sociology of the family can be broken down to three major approaches, each with its own strengths and weaknesses; which need be employed in a study, then, relies largely on the subject of, and questions posed by, the research.
One approach is survey research of contemporary families. This holds the benefit of leaving statistical data and large and hopefully random samples from which a researcher can interpolate the general traits of a society. However, survey respondents tend to answer as would feel regular or ideal rather than as things might actually be. It also gives a very one-sided explanation view of a larger group, which does not sufficiently allow for contention. The information is often outdated, not representing the true statistics of the world. The information can also be deceiving and not represent the true points that the surveys and graphs are representing.
Another method is ethnographic research of families. Where surveys allow for broad but shallow analyses, observation allows sociologists to obtain rich information on a source of a much more limited size. It allows the research an "insider" perspective, and through this closer look, a better idea of the actual social framework of families. Where surveys are strong, however, ethnographic research is weak. By reducing the size of a sample size, it may be no longer evident as to how representative the family being researched on is, to families at large within a society, and then also does not allow much room in linking the specific traits of the families being observed to a society more generally.
Finally, a researcher can use documented studies of families from the past as a source of information. These sources may include very personal items (such as diaries), legal records (census data, wills, court records), and matters of public record (such as sermons).
