I’m establishing an open prize competition for the best comprehensive quantitative dynamical model of US society given a standardized table of measures. The openness of the table requires aggregation. The importance of jurisdiction requires geographic aggregation. The dynamics require longitudinal range. Comprehension requires a wide latitude of measures.
It would be best to use the same geographic aggregation across time and measures.
State-level does not provide enough samples.
What would be the best choice of geography?
If a single choice does not suffice to provide a broad range of both longitude and latitude, what would be the best set of geographic aggregations?
