Objectives
Build and demonstrate the potential of micro-datahistorical census datasets
Why?
Because it hasn’t been done before!

Problem
Non-compatible geographical datasets
So?
Impossible to trace changes at the lowest dataaggregation level

Small-area / census tracts datasets
• Lowest level of aggregation for official data.
• Unique and indispensable information for the definition of public developmentpolicies and for decision-making as regards investment by the public and pri-vate sectors.
• Consistent grouping in terms of tabulation data and microdata available (6 setsof tables)
Geographical information for small areas: strengths and some weaknesses.
