  1. Unclear status of data for 1950-60

    The 2016 WDI go back to 1960 for the longest series. However, if one consults earlier WDI from the archive, key series such as "population, total" are available from 1950 onwards.

    Suggestion: It would make long-run analyses much more convenient if you could provide the data from 1950 on for such series in the lastest WDI.

    If you have less trust in the data between 1950-60 and this is why you decided to discard them, you could harmonize the measurements to the best of your knowledge and add a "cautionary note" about this data so that users can decide themselves…

    Thank you for your message. There was only one year (1995) when certain data from 1950 to 1959 were included in the World Development Indicators. Kindly refer to other sources of data for indicators available before 1960, such as the UN or the IMF.

  2. I cannot find BOD (biochemical oxygen demand) data in WDI anymore!

    BOD is a measure of water pollution. It was available in earlier versions of WDI but now i cannot find it anymore. Any reason?
    Do you know how we can get this information?

    Unfortunately, we no longer have data on BOD. This indicator was removed because the were no updates available in the dataset from which this information was previously sourced.

  3. Do you have historical data for the SDR deflator?

  4. Regional Data for all indicators

    I was trying to find regional data for some indicators but could only find information by nation. Regional data was only available for featured indicators. It would be helpful if Regional Data was available for all indicators together with national data

    Unfortunately, we cannot provide regional aggregate data for indicators where geographic coverage across countries is not sufficient. It could be misleading to our users to state a regional aggregate based on data coming only from a few countries. We hope to achieve this in the future as we get better data coverage. Please do let us know if you are interested in a particular indicator. Many thanks for the feedback!
