Timeliness vs. Quality vs. Completeness
JODI data are short-term data
Availability and quality of early data
Revisions to first released information
Consistent methodology help make data useful
Trends and levels
Balance Timeliness, Quality and Completeness

Data Characteristics
JODI o Short term preliminary
data
o Monthly M-1
o Key data Supply Side
o Seasonality analysis
Annual data
o Final annual data
o Annual Y-2
o Supply and Demand
o Higher level of detail
JODI Early key data for over 90 countries Provide basis for early analysis of markets Sum of 12 months not comparable to annual data
© OECD/IEA 2015
Increased interaction of JODI users and data producers
Users Share knowledge – Use JODI Forum
On data issues and market analysis With other users and JODI partners
Increase understanding of data issues Help identify potential areas of development
Data providers/administrations/organizations Awareness/understanding of how data are used Visibility of output and its impact on analysis Access to Forum, etc.
