Datasets:

For a single dataset, the citation should be based on the citation used in the final report, but with a number of additions:

Insert "[Dataset]" after the title of the survey.
Follow this with the name of the dataset, e.g. IDIR31.SAV. If there are multiple datasets for a survey, list them if possible. If too many, this can be omitted.
Follow the list of institutions involved in the report with "[Producers]".
Add "ICF [Distributor], year" to the end with the year the dataset was made available for distribution (typically the same as the year of publication of the report).
For example, for the 2016 Timor-Leste DHS recode data set, use a citation such as:

General Directorate of Statistics [Timor-Leste], Ministry of Finance [Timor-Leste], and ICF. 2018.
Timor-Leste Demographic and Health Survey 2016 [Dataset]. TLIR71.DTA. Rockville, Maryland: General Directorate of Statistics, Ministry of Finance, and ICF [Producers]. ICF [Distributor], 2018.

Multiple Datasets (more than 3) from multiple countries:

ICF. 2004-2017. Demographic and Health Surveys (various) [Datasets]. Funded by USAID. Rockville, Maryland: ICF [Distributor].

If the recode manual is used, that should be referenced separately, as should other documents that are used.
