Using existing research and surveys, this paper presents statistics relating to the formation, duration, quality, and characteristics of marriage among low-income couples in the United States. It finds that low-income couples are as likely as their more affluent counterparts to marry, but that their relationships are more unstable and experience higher rates of dissolution. Furthermore, low-income couples are more likely to experience a premarital first birth, marry at a younger age, have lower levels of education and employment, and rely on government assistance programs.
