Description

Small-area census data are a critical resource for local and neighborhood-level analyses of population and housing, but the basic framework used to produce data for census tracts and smaller geographic units also necessarily complicates their utility. For example:
- The modifiable areal unit problem (MAUP) is especially relevant for small areas, as slight variations in how boundaries are drawn can have a big impact on resulting population statistics.
- Constraints on census sampling methodology—particularly for the American Community Survey—limit the reliability of small-area summary statistics.
- Analysis over time is complicated by boundaries that change with every decennial census.

Even as these issues gain greater recognition, advancements in computing power and data resources (including both public and restricted-access data) are opening up new possibilities for analysis at higher precision using:
- Census block data
- Gridded population data
- Individual-level microdata
- Census data combined with other sources

Papers in this session investigate both the limitations and possibilities associated with using fine-scale census data. The papers may address these issues head-on, or they may encounter these problems in application, employing novel solutions.
