This measure will be determined from Pearson-type correlations of a relevant long-time settlement-level data (tax, income, population size, etc).
We have found freely available data on the Internet for U.S.A on county level (GPS coordinates [37] and population census data for the last 5 census, [38]), and for Transylvania on settlement level (GPS coordinates [39] and population census data for 11 census between 1850 to 2002 [40]).
To do that they need individual level data.
You can download the local authority level data here.
At the settlement level, 21 of the 194 sampling points were replaced for various accessibility reasons, a customary number of settlement-level replacements".
In the historical reconstruction (1825 1999), simulated aboveground C recovered to roughly 60% of the pre-European settlement levels in 1999, in agreement with historical data from the region [26].

However, in the face of China's macro level population census data, variables that can be used as quantitative comparison and analyzing factors are usually limited to the ethnic groups' population scale, the social-structure characteristics of the population, ethnic population settlement levels, linguistic differences between ethnic groups, and so on.
However, there is some state-level data.
The connections between profile location, settlement, isotope data, and P levels enable the identification of both agriculture production zones and enhanced understanding of stable C isotope dynamics in soils within the unique physiographic and archaeological surroundings of the Maya Lowlands.
