Abstract
The total fertility rate in rural Tanzania is nearly four times higher than the global rate. In the northern rural Meatu District, only 12 percent of women are using contraceptives, although 89 percent report wanting to delay or prevent pregnancy. This study evaluates the effect of a family planning program designed to improve information about contraceptives through a randomized control trial. I estimate the effect of asymmetric spousal information, randomizing the inclusion of husbands in household consultations about family planning. I find that the informational treatment had a significant effect on reducing pregnancies. Women who benefited from asymmetric information and consulted with a family planning worker alone (without their husbands) reduced pregnancies by a significantly larger amount (16 percentage point). This research provides support for community-based health services and demonstrates the trade-offs of providing asymmetric information to spouses.

Experimental Details
Interventions
Intervention(s)
Community family planning workers were trained on basic sexual health and maternal health. They were employed to make bi-monthly visits to women or couples in the treatment villages to discuss family planning options. In half the treatment villages, men were included in these consultations, in the other half, men were excluded.

Experimental Design
Experimental Design
The study sample includes 660 households across 12 villages in rural Meatu district. Four villages are assigned to the couples treatment (receiving family planning information as a couple), and four villages are assigned to the individual treatment (women receive family planning information alone). The treatment duration was 14 months. Data was collected during the four month period before and after the intervention.
