Aiming to update the economic, demographic, and social characteristics and housing conditions of the population, Morocco conducted its last General Population and Housing Census (GPHC) in 2014. Accurate data on age is a key element for decision making, and necessary to build policies and improve health indicators. The main objective of this paper is to assess the quality of age reporting in the 2014 Morocco census. We found that grouped age data was of poor quality in two regions. More attention should be paid to improving data quality in those regions in the coming census, especially among men.

The National Survey on Population and Family Health (NSPFH) is an important source of data in Morocco. Its objective is to assess, periodically, the state of population health and the impact of policies and programs put in place, by updating the main demographic and health indicators. The report of the sixth NSPFH, conducted during the period October 2017-January 2018, illustrates updated socio-demographic data and the new prevalence of several diseases. As the NSPFH results are a reference for decision-makers, researchers and professionals, it seems necessary to promote them and give them more credibility. The objective of this paper is to verify the reliability of the NSPFH data and results using demographic data quality assessment methods (graphic methods: age-gender pyramid and distribution by gender and area of residency, and statistical methods: non-response rate and age accuracy indexes) to ensure if they are of good quality. This study showed that the NSPFH-2018 data were of good quality. Indeed, the non-response rate did not exceed 1.1% for all questionnaires (household 1.1%, woman 0.5% and elderly 1.1%). The age-gender pyramid confirmed the demographic transition towards ageing and the downward trend of fertility in Morocco. The distribution by area of residency confirmed the trend towards urbanization of the country (61% urban and 39% rural). The Whipple (1.05), Myers (4.73), Bachi (2.31) indexes and the United Nations Combined Index (31.21) were all within the standards for a good quality of age declaration. In addition, the results were consistent with each other and in line with the national and international health context.

According to the World Health Organization, diabetes is the cause of 1.5 million deaths each year, 80% of which occur in low- and middle-income countries. It will become the principal cause of death by 2030. In Morocco, the situation is as alarming as at the global level. However, the prevalence of diabetes at the provincial level is unknown. This paper aims to present partial results obtained from a statistical study, carried out in February 2021, where we estimated the prevalence of diabetes and studied some socio-demographic determinants among the diabetic population living in Salé, Morocco. The investigation included a sample of 488 households selected according to a two-stage stratified probabilistic sampling plan (466 of which were surveyed (i.e. 1868 individuals) with a response rate of 466/488 =95.5%). The results showed that, in 2021, diabetes was affecting 5.5% (95% CI 4.5%, 6.6%) of the studied population (5.8% of women and 5.1% of men, 5.6% in urban areas and 4.5% in rural areas). The proportion of diabetics increases significantly with age (p-value=0.0001<0.05). It was 0.1% among young people (<18 years), 3.9% among individuals aged 18-59, and 26.9% among those aged 60 and above. A logistic model, making it possible to predict, with an accuracy of 91.7%, the risk of contracting diabetes among the population aged 18 and above (1,308 subjects, 7.8% of which were diabetic), was performed. The model included several socio-demographic determinants. Age, educational level, economic activity, average household income and smoking were significantly associated with diabetes.
