From the article:
"...Indeed, a 2001 research report from the National Institute of Justice found that rates of violence in couples experiencing high levels of financial stress were 3 1/2 times the rates in couples with low levels of stress — rising to 9.5 percent from 2.7 percent. According to a working paper by the Center for Global Development, the effects of unemployment on IPV vary across populations due to cultural differences, but in the U.S., the NIJ found in 2009 that periods of unemployment by a man in a heterosexual relationship are correlated with significantly elevated rates of abuse. That paper didn’t show a causal link but found that couples in which the man was employed had a 4.7 percent prevalence of abuse, while that figure was 7.5 percent for couples in which the man experienced one period of unemployment and 12.3 percent for couples in which the man experienced two or more periods of unemployment..."
