This paper presents the results of a meta-analysis examining the overall impact of 23 livelihoods projects evaluated as part of Oxfam GB's Effectiveness Reviews between 2011 and 2016.

Results show a statistically significant, positive impact on the welfare of participants, measured by household consumption and wealth. Analysis indicates an increase in household consumption of approximately 6.6% (95% confidence interval from 1.6% to 11.9%). While some projects had more positive results than others, these differences are not explained by regions, whether the country has lower-income or middle-income status, whether households were initially poorer than average, nor by project scale, budget or duration.

However, there is some evidence that female-headed households have tended to benefit less from the projects than male-headed households. Projects that targeted a specific agricultural product or products (such as vegetables, coffee or dairy production) were generally found to be successful in promoting production and sales.
