From National to Local: A New Way to Leverage DHS Data

In DHS survey final reports, data are presented on a national or first-level administrative sub-national level. However, this is usually not the level at which program planning and decision making are truly happening. To support more decentralized decision making at lower administrative levels, data need to be presented on a more disaggregated level.

The DHS Program is producing a standard set of spatially modeled map surfaces for each population-based survey for a select list of indicators that provide smaller area estimates of data. Geostatistics are used to predict (interpolate) the indicator value for unsampled areas based on data from sampled data locations. DHS creates standardized modeled map surfaces using DHS survey data along with global covariate datasets. Currently, sets of standard surfaces are available for 16 surveys. Spatial data packages and stand-alone maps are available for download through The DHS Program’s Spatial Data Repository.

How can modeled map surfaces be used?

These new spatially modeled surfaces can help in several ways to improve decision making for many development sectors that include health, population, nutrition, and water and sanitation programs on multiple levels. Users can combine the maps with other resources to support:

  1. Monitoring and evaluation: analysis and evaluation of past initiatives (impact analysis) or understanding existing situations
  2. Program planning: future planning of appropriate programs and policies

Data in the modeled surfaces can be used to evaluate past programs or to better understand existing situations. Such evaluations can help to understand deviations from the norm, attribute cause, or to contribute to impact evaluations, which analyze what would have happened to the population of an area if a program had not been implemented.

Program managers can also use modeled surfaces to plan, target, and develop interventions and programs that aim to improve situations in targeted geographic areas. Interventions can be targeted more precisely, saving money, time, and human resources in the search for the most effective outcomes.

The matrix below shows potential approaches for monitoring and evaluating past and planning future programs using modeled surfaces.

This matrix is by no means comprehensive, and it is expected that map users will come up with many more potential uses after analyzing their particular situation and maps for their country.

To read more, please see the Spatial Analysis Report 14, “Guidance for Use of The DHS Program Modeled Map Surfaces.” The report delivers more in-depth information on what modeled surfaces The DHS Program is creating, as well as an explanation of their creation process. In addition, the report provides guidance on limitations and assumptions.

The DHS Program is looking forward to seeing how groups will use this new data product to enhance their activities. There is enormous potential for innovative uses of these modeled surfaces beyond those discussed in the report. Users are encouraged to submit ideas and case studies to The DHS Program (spatialdata@dhsprogram.com) as only a large community of users who share their experiences will fully expose the maps’ potential.

Enfin, STATcompiler et l’Appli Mobile du DHS Program disponibles en français

L’attente est finie! Le STATcompiler et l’Appli Mobile du DHS Program sont désormais disponibles en français.  Saviez-vous que 30 % des enquêtes du DHS Program sont réalisées dans pays francophones ? Notre objectif est d’augmenter l’utilisation de nos données par nos collègues francophones.  Ces deux outils placent plus de 250 enquêtes de 90+ pays au bout de vos doigts et ils satisferont vos besoins des données démographiques et de santé numériques.

Le STATcompiler permet aux utilisateurs de créer des tableaux personnalisés et visualiser les données avec des histogrammes, graphiques linéaires, et cartes thématiques. Arrivé à la page d’accueil de STATcompiler, les utilisateurs peuvent choisir leur langue préférée: Page d'accueilfrançais ou anglais. Si vous êtes en milieu francophone, les paramètres de STATcompiler choisiront automatiquement le français comme la langue de défaut, ainsi que l’anglais pour ceux en milieu anglophone. N’inquiétez pas, vous pouvez toujours changer la langue en sélectionnant  « English » ou « Français »  comme le graphique à gauche indique.

 

Commencer en choisissant les indicateurs et les pays qui vous intéressent. Un tableau sera produit avec les données que vous avez choisies.

Tableau et indicateur

 Après, visualiser ces données avec des histogrammes, graphiques linéaires, et cartes thématiques. Voilà, une carte des ménages qui disposent d’électricité.

L’Appli Mobile présente 125 indicateurs pour toutes les enquêtes du DHS Program, y compris la désagrégation par des caractéristiques sociodémographiques, telles que régions infranationales, niveau d’instruction et quintiles de bien-être économique. L’Appli Mobile permet aux utilisateurs à explorer par pays ou par indicateur pour voir les tendances et les comparaisons entre les pays. Vous trouvez-vous loin d’une connection d’internet? L’appli est aussi disponible pour l’accès en mode déconnectée.

promptLes utilisateurs actuels de l’Appli seront avertis par un message sur l’écran d’accueil de l’appli qui indique qu’elle est maintenant disponible en français et fournit des instructions pour comment changer les paramètres des langues. Pour les nouveaux utilisateurs, l’Appli ouvrira la premère fois selon les paramètres de langue de l’appareil. Les utilisateurs anglophone pourront tous basculer facilement entre les deux langues dans les paramètres de l’Appli.

Télécharger l’Appli Mobile gratuitement pour les appareils Android et iOs.
