Downloadable Data

Downloadable data refers to data that is made available on-line so that the user will be able to save the data files on his/her computer. Select this option if you are only interested in data that can be easily accessed from the Internet without a need to contact the data providers. Such data might be downloadable directly from DDCN or from other websites. 

Data Free of Charge

Select this option if you want to narrow down your search to avoid retrieving data sets that need to be purchased.  It refers to data publicly available at no cost to the user.  

Data Time Period

If you are searching for data covering a particular time period (e.g. early transition 1990 - 1995) select from the drop down menu the option that is closest to your needs. This will help narrow the search and return only those datasets that refer to the selected time interval.

Macro/Micro

Macro data refers to data at the national level, as opposed to micro data which includes individual, household and firm level data. Typical examples of macro data are country level time series of GDP per capita, inflation, etc.  Examples of micro data are surveys and registry data.  Select one of these two categories to help you find the data that you are most interested in.

Cross Section/Panel

This drop down has three options. Select the one that best fits your research purposes to narrow down the search.
Cross Section: Survey data from a set of units at one particular point in time.
Time Series: Observations of a variable made over time. Time Series can also be constructed from cross sectional studies if the same questions are asked more than once over time.
Panel (Longitudinal): the same individuals (or households, or firms) are interviewed over time. 

EXAMPLE
