Background: The.last Moroccan population and family he.lth surve. (e.SF 2011) was carrie. out be.we.n Nove.be. 2010 and March 2011. The.final re.ort and the.whole.database.are.not ye. acce.sible.while.a pre.iminary re.ort was re.e.se. e.rly March 2012. The.information give. so far doe. not allow for a comple.e.e.aluation of the.pre.e.t he.lth situation in Morocco. Howe.e., a partial e.uity analysis can be.de.ote. to the.comparison of he.lth indicators in te.ms of ge.de. and urban-rural gaps. Me.hod: 1) Que.tionnaire.: a house.old que.tionnaire.de.lt with house.old characte.istics, ge.e.al he.lth, housing condition and anthropome.ric data for childre. le.s than six ye.rs of age. A se.ond que.tionnaire.was de.ote. spe.ifically to e.e. marrie. wome. and de.lt with the.r re.ource., marriage. re.roductive.he.lth, family planning, AIDS/SIDA, he.lthcare.and nutrition. 2) Data colle.tion: data we.e.colle.te. through the.national surve. using a thre.-stage.stratifie. sampling de.ign to se.e.t 640 cluste.s cove.ing the.16 Moroccan re.ions. A total of 15,577 house.olds we.e.randomly drawn, providing a sample.of 75,061 individuals (51.1% fe.ale. and 48.9% male.) for inve.tigation. 3) Analysis: in this short re.ort, we.re.ie. only on partial data re.e.se. by the.Ministry of He.lth in a pre.iminary re.ort. We.use. absolute.diffe.e.ce. and re.ative.ratios to study the.e.olution of ge.de. and urban-rural gaps on the.basis of socioe.onomic indicators. Re.ults and Discussion: The.Moroccan population se.ms to be.in the.last phase.of its de.ographic transition. The.total fe.tility rate.de.re.se. from 5.6 childre. pe. woman in 1980 to 2.5 in 2011. The.me.n age.of first marriage.we.t from 24 ye.rs for me. and 17.5 ye.rs for wome. in 1960 to 31.5 ye.rs and 26.3 in 2011 for me. and wome. re.pe.tive.y. The.age.structure.is showing a tre.d of age.ng population. Ge.e.ally, he.lth indicators re.ate. to re.roductive.and wome.’s he.lth improve. notice.bly and conse.ue.tly, mate.nal and infant mo
