Sampling procedure

L'enquête PROSEHA est une enquête statistique par sondage qui a porté sur un échantillon représentatif à l'échelle nationale et régionale. La procédure retenue pour le tirage de l'échantillon était aléatoire et stratifiée à deux (2) degrés. Au premier degré, 222 ZDs (à enquêter dans les strates) ont été tirées de manière aléatoire et proportionnellement à la taille de chaque ZD (en termes de nombre de ménages). Au second degré, 20 ménages ont été tirés aléatoirement dans chaque ZD après un dénombrement exhaustif. Ces 20 ménages tirés ont fait l'objet d'interviews avec un questionnaire ménage. Parallèlement à ces interviews directes auprès des ménages, des tests sur la qualité de l'eau ont été effectués dans les ménages et au niveau des sources d'eau. Dans chaque ZD échantillon, un test à blanc (qui sert à tester les outils), deux tests de la qualité de l'eau des sources (les plus fréquentées) et trois tests de la qualité de l'eau des ménages (sélectionnés aléatoirement parmi les 20 ménages à enquêter) ont été effectués. Au Il convient de rappeler que les indicateurs utilisés pour la détermination de la taille de l'échantillon sont ceux issus de l'enquête sur la situation de référence réalisée en 2018. Il s'agit de la proportion des personnes ayant accès au service de l'eau potable gérée en toute sécurité (service optimal), la proportion de la population utilisant des sources non améliorées de l'eau, la proportion de la population utilisant des installations élémentaires de lavage des mains. L'indicateur retenu est celui qui maximise la taille de l'échantillon. La taille de l'échantillon devant assurer la représentativité pour chaque région, pour l'ensemble du Niger et selon le milieu de résidence (ensemble milieu urbain et ensemble milieu rural).
La détermination de la taille de l'échantillon est basée sur la formule suivante : Où

n est le nombre de ménages à sélectionner (voir tableau N°1 suivant); est le quantile d'ordre) de la loi normale réduite centrée, au carré (ici t=1,96) ; est la marge d'erreur absolue associée au niveau de confiance ( associée à l'estimation p ; (m=0,05) p est la prévalence de l'indicateur à mesurer (voir annexes) ; d est l'effet imputable à la conception de l'échantillon (1,5)et est le taux de non-réponse (5%). L'échantillon issu de cette formule a été majoré de sorte à tenir compte des éventuelles pertes (ou non réponses) tout au long de la période de collecte. Globalement, le taux de couverture de l'enquête est de 97%, ceci signifie que sur les 4 568 ménages attendus, 4 429 ont pu être enquêtés avec succès dans les huit régions du Niger. Le tableau ci-dessous présente la répartition de ce taux selon les régions.

Africa has the youngest population in the world. Among the 35 countries with the lowest median age worldwide, only three fall outside the continent. In 2023, the median age in Niger was 15.1 years, the youngest country. This means that at this age point, half of the population was younger and half older. A young population reflects several demographic characteristics of a country. For instance, together with a high population growth, life expectancy in Western Africa is low: this reached 58 years for men and 60 for women in 2024. Overall, Africa has the lowest life expectancy in the world.

Africa’s population is still growing Africa’s population growth can be linked to a high fertility rate, along with a drop in death rates. Despite the fertility rate on the continent following a constant declining trend, it remains far higher compared to all other regions worldwide. It was forecast to reach 4.02 children per woman, compared to a worldwide average of 2.25 children per woman in 2024. Furthermore, the crude death rate in Africa overall dropped, only increasing slightly during the coronavirus (COVID-19) pandemic. The largest populations on the continent Nigeria, Ethiopia, Egypt, and the Democratic Republic of Congo are the most populous African countries. In 2025, people living in Nigeria amounted to over 237 million, while the number for the three other countries exceeded 100 million each. Of those, the Democratic Republic of Congo sustained the fourth-highest fertility rate in Africa in 2023. Nigeria and Ethiopia also had high rates, with 4.48 and 3.99 births per woman, respectively. Although such a high fertility rate is expected to slow down, it will still impact the population structure, growing younger nations.
