About Our Data Products

AidData engages in a variety of data collection and value addition activities to publish its ever-expanding suite of data products. Data collection takes place along two distinct product lines: Aggregate Data (or data represented as a single, composite value) and Project-Level Data (or data consisting of distinct, project activities with accompanying project information). AidData's data is sourced from various locations, including but not limited to the OECD-DAC's Creditor Reporting System (CRS), donor systems (such as official data from individual donor governments), and recipient systems (such as Aid Information Management Systems). Value addition activities include (1) activity and purpose coding, (2) geocoding (to produce our expanding repository of sub-national, geospatial research datasets) (3) data curation (the linking, deduplication and presentation of project records gathered from different sources or data collection activities), and (4) data quality assurance (the transformation and verification of data according to standard AidData practice). AidData also collects official project-level data on the development finance activities of non-OECD bilateral and multilateral donors, as well as data on Chinese development finance, collected using AidData's unique Tracking Under-reported Financial Flows (TUFF) methodology.     
Please read AidData's Data Management Plan (DMP) for more descriptions of each of these activities and products. The DMP details the full range of data products that AidData generates and the underlying processes used for each product, as well as provides a framework for upcoming data projects and releases.

Data Product Processing Levels

AidData's data products are built using hierarchical data processing levels, numbering 1-4 (with sub-processing Levels like Level 1a). Each processing level is built upon the previous level (meaning the Level 1 product is derived from the Level 0 product and so on). Table 1 below lists the processing levels used by AidData in data production, with their notional meanings and descriptions.

AidData Data Level  

Description (AD)

Level 0

Minimally processed raw data to Level 0 field names and table structure per the product line, converted to UTF-8. This product is for internal use only. This data will never be part of a public release.

Level 1

Data post processed to Level 1 field names; Data decomposed to proper table structure by the product definition; financials deflated to base years where possible. Sectors crosswalked to aiddata sectors. Geocoded data is spatially scrubbed (verified to be in the correct boundary). Fields checked for intra and inter field consistency. Level 1 stats generated. Quality assurance (QA) flags added. This Level may include ancillary data included in the release, but is not quality assured by AidData. This is the first data product which is available as a public release.

Level 1A

A single table, denormalized version of the Level 1 product, with provided assumptions. This is a ‘joined’ product of Level 1 constituent tables or data.

Level 2
(Planned Product)

Level 1 + any quality assured ancillary data (e.g. evaluation data); Aggregates and rollups of data by a data dimension (e.g. by Sector or Donor)

Level 2A
(Planned Product)

Rasterizations - Continuous surface representations of our Aid Information.  For geocoded data, a geospatial representation of (a) the total dollars of aid we estimate are at a given location, and (b) the number of projects.  This product additionally provides at least one surface of the uncertainty in our continuous estimates.

Level 2B
(Planned Product)

Simulated Products - These products are further refined versions of the Level 2 product line.  For example, a product might produce a continuous surface estimate of aid projects that is weighted to account for slope, population, or road networks.  These products will also provide a surface of uncertainty.
