Great care and attention are paid to data continuity, revision, methodology and classification. It is a company policy that our staff ensures that our data always reflect the latest definition and full consistent history. Data series that have been discontinued because of changes in the methodology of collection or compilation but have a longer history are highlighted in separate sections.


Our data are all extracted directly from official records, publications and websites. The primary source of our data comes from central banks, statistics offices, finance ministries, stock exchanges, other government and semi-government bodies, and professional associations.

We keep close contact with these organizations, many of which have special arrangements with us, which enable us to receive data files directly for uploading to our databases on a continual basis. Internally, we have strict control procedures and specialist devices for checking data accuracy for both electronic file handling and data entry by human hands.


We have the most comprehensive economic databases for emerging markets. Our databases contain hundreds of thousands of data series. The majority are monthly, supplemented by daily, quarterly, semi-annual and annual data. Most data series start from when they first became available.

When comparing our databases with others, one should note that many data vendors adopt the practice of putting in their databases the same data in different frequencies (e.g., monthly, quarterly and annual) or creating new series by manipulating the data themselves (e.g., seasonally adjusting the data or calculating some ratios).

At EMED, we include only the highest frequency series and let our users conduct their own analysis using the sophisticated functionalities available on our versatile platforms. Actually, given our platforms, we could easily double, triple or even quadruple the size of our databases in no time, if we wanted to. However, we do not believe in boosting the size of our databases for the sake of it, which actually adds nothing to the comprehensiveness – in terms of the amount of information – of our databases. As a matter of fact, while we keep adding new data to our databases, we also often remove data unused or very sparingly used – based on usage traffics – from our databases.


EMED does not only supply data. It considers responding to clients' requests and answering clients' questions a crucial part of its service.

From experience, our professional staff can often provide satisfactory answers to most questions on the spot over the phone. For questions that we need to seek clarification from data sources, e.g., data are revised following a change in their definition, the turnaround time is usually short because we keep close contact with the officials of data sources.

In all cases, it is our policy to respond to clients within 24 hours.
