Specify a comma separated list of country ids to filter by. For a list of countries use dhs_countries(returnFields=c("CountryName","DHS_CountryCode"))


Specify a comma separated list of indicators ids to filter by. For a list of indicators use dhs_indicators(returnFields=c("IndicatorId","Label","Definition"))


Specify to filter data from the latest survey by including `selectSurveys=TRUE` in your request. Note: Please use this parameter in conjunction with countryCode, surveyType, or indicatorIds for best results.

Specify a comma separated list of survey years to filter by.


Specify a range of Survey Years to filter Surveys on. surveyYearStart is an inclusive value. Can be used alone or in conjunction with surveyYearEnd.


Specify a range of Survey Years to filter Surveys on. surveyYearEnd is an inclusive value. Can be used alone or in conjunction with surveyYearStart.

Every survey is assigned a surveys status and can be queried based on the surveyStatus parameter. `surveyStatus="available"` (default) provides a list of all surveys for which the DHS API contains Indicator Data. `surveyStatus="Completed"` provides a list of all completed surveys. NOTE: Data may not be available for every completed survey. `surveyStatus="Ongoing"` provides a list of all ongoing surveys. `surveyStatus="all"` provides a list of all surveys.


Specify a survey characteristic id to filter surveys with the specified survey characteristic. For a list of survey characteristics use dhs_surveys(returnFields=c("SurveyId", "SurveyYearLabel","SurveyType","CountryName"))


Specify a tag id to filter surveys containing indicators with the specified tag. For a list of tags use dhs_tags()


You can specify the format of the data returned from the query as HTML, JSON, PJSON, geoJSON, JSONP, XML or CSV. The default data format is JSON.


Specify a list of attributes to be returned.


Specify the number of results to be returned per page. By default the API will return 100 results.

If the API request should be cached, then provide a client object created by client_dhs


Should we force fetching the API results, and ignore any cached results we have. Default = FALSE


Boolean for if all results should be returned. If FALSE then the specified page only will be returned. Default = TRUE.


Returns a data.table of 28 (or less if returnFields is provided) surveys with detailed information for each survey. A detailed description of all the attributes returned is provided at


if (FALSE) {
# A common use for the surveys API endpoint is to query which countries
# have conducted surveys since a given year, e.g. since 2010

dat <- dhs_surveys(surveyYearStart="2010")

# Additionally, some countries conduct non DHS surveys, but the data for
# thse is also available within the DHS website/API. To query these:

dat <- dhs_surveys(surveyType="MIS")

# Lastly, you may be interested to know about anything peculiar about a
# particular survey's implementation. This can be found by looking within
# the footnotes variable within the data frame returned. For example, the
# Madagascar 2013 MIS:

dat$Footnotes[dat$SurveyId == "MD2013MIS"]

# A complete list of examples for how each argument to the surveys API
# endpoint can be provided is given below, which is a copy of each of
# the examples listed in the API at:
