# Where have I got to? Associations of age at marriage with marital household assets in educated and uneducated women in lowland Nepal

## TL;DR

This study examines how the age at which women in Nepal marry relates to the wealth of their marital households, and how this varies by education level.

## Contribution

The study investigates the association between marriage age and marital household wealth, distinguishing between educated and uneducated women in Nepal.

## Key findings

- For uneducated women, marrying later was associated with higher marital household asset scores.
- Educated women who married later had higher marital household asset scores, but the effect varied by education level.
- Delaying marriage beyond 16 years had modest benefits for marital wealth among uneducated women.

## Abstract

Women’s underage marriage (<18 years) is associated with adverse maternal and child health outcomes. Poverty in the natal household has been widely considered to be a key risk factor for underage marriage, but the evidence base is unreliable. When investigating this issue, most studies use marital wealth inappropriately, as a proxy for wealth in the natal household. In contrast, we investigated whether the timing of women’s marriage was associated with the wealth of the households they marry into, and how this may vary by women’s education level. This approach allows us to explore a different set of research questions which help to understand the economic value placed on the timing of women’s marriage.

We used data on 3,102 women aged 12–34 years, surveyed within 1 year of marriage, from the cluster-randomized Low Birth Weight South Asia Trial in lowland rural Nepal. Linear mixed-effects regression models investigated independent associations of women’s marriage age and education level with marital household wealth, and their interactive effects. Models adjusted for marital household traits. We analysed the full sample, and then only the uneducated women, who comprised a substantial proportion in our sample.

In the full sample, we found that each later year of women’s marriage was associated with 1.5% lower asset score for those with primary education, and with 0.3% and 1.3% higher asset score for those with lower secondary or secondary/higher education, respectively. For uneducated women, relative to marrying ≤14 years, marrying at 15, 16, 17 and ≥18 years was associated with 1.5%, 4.4%, 2.4% and 6.2% greater marital asset score respectively.

On average, marrying ≥18 years was associated with greater marital assets for secondary-educated women. There were only very modest benefits in terms of marital household wealth for delaying marriage beyond 16 years for uneducated women or those with low education. These findings elucidate potential trade-offs faced by families, including decisions over how much education, if any, to provide to daughters. They may help to understand the economic rationale underpinning the timing of marriage, and why early marriage remains common despite efforts to delay it.
