The survey data show that 7.5 percent of women from the richest households have married men who are 10 or more years older than themselves. Similarly 10. 7 percent of women in the fourth category as per the wealth index have married husbands 10 or more years older than themselves.
Only 3.1 percent of women from the poorest families have husbands 10 or more years older than themselves. Likewise, 35.4 percent of women from the richest households have married men five to nine years older than themselves as have 37.5 percent of women in the fourth category.
CBS said that facilities such as computers, mobile phones, television and vehicles, and the condition of their houses where taken into consideration while categorizing the women on the wealth index.
The data also shows that 10 .5 percent of women with higher education have married men 10 or more years older than themselves. Likewise, about 30 percent of women with higher education have married five to nine years older husbands. Only 6.6 percent of illiterate women have married 10 or more years older husbands.
"Women in the eastern tarai were more likely to be married to men 10 or more years older than themselves," the report stated. Women in richer households were more likely than other women to have older spouses, it is also stated.
"The study shows that educated women from well-off families tend to be married to older husbands," Suresh Basnet, director at CBS, said.
