The present study examined the economic well‐being of disabled and nondisabled men and women in the United Kingdom. Using the 2009–2014 Life Opportunities Survey (N = 6,159 adults), the study is the first longitudinal study to empirically compare the economic well‐being of disabled women in contrast to disabled men and nondisabled men and women. Hierarchical linear modelling and hierarchical linear logistic modelling were used to estimate the longitudinal changes. Findings indicate that, overall, disabled women’s economic well‐being improved significantly between 2009 and 2014 even after controlling for other demographic characteristics. However, the improvements were not substantial enough to significantly narrow the economic disparities between disabled women and disabled men and nondisabled men and women. Disabled women remained worse off than disabled men and nondisabled men and women in 2014 as they did in 2009. The findings indicate that intersectional discrimination against disabled women exist in the United Kingdom. Findings from this study provide empirical evidence to support policies that enhance the economic security of disabled women.
