- Massive volumes of federal, state, and local statistical
information=> need for good filtering support.
- Federal, state, and local statistical providers use a variety of
standards, formats, terminology, and practices for collecting and
disseminating statistics=> need for metadata interoperation.
- The full population includes people with diverse user needs,
experiences, and technological platforms=> need for multiple,
alternative solutions.
- The level of statistical/numerical literacy in the population is
generally low=> need for online help and support.
