Introduction
The office of the president, along with the Statistical Yearbook, maintains lists of areas and administrative mutations. We have synthesized these into coherent annual lists ("geo code vintages") at the two levels, which you can use to answer questions like "at time T, what are the component cities C of region R? We account for the three possible circumstances:
- The boundaries of an existing area change, but its name is retained -- Replace the area by declaring a new geo code, and substitute into the "after" vintage.
- A new area is created, usually in conjunction with the redefinition of an existing area -- Declare a new geo code, and add to the "after" vintage.
- An existing area is terminated, usually because it has fissioned -- Retire the geo code from the "after" vintage.
Note that a geo code may remain in statistical use even after the area has been terminated as an administrative entity. We do not double-guess our historical sources.
