One issue is that cities without populations in populationtablecorrected but in roundleveloutput2 get dropped later.

Files and data
The files are in:
E:\McNair\Projects\Ecosystem\Ranking
The main SQL file is:
Ranking.sql
This file works on the database cities.
However, the cities database takes vc data from vcdb2. See VC Database Rebuild for information on the build.
The output from vcdb2 is roundleveloutput2, which is exported as roundleveloutput2.txt
roundleveloutput2.txt is imported into cities as roundleveloutput2, and then left joined with populationtablecorrected. This is done in last.population.sql, which is in
Z:\Hubs\2017\sql scripts
Population issue
One issue is that cities without populations in populationtablecorrected but in roundleveloutput2 get dropped later. For example, roundleveloutput2 contains Brooklyn, NY but populationtablecorrected doesn't (its New York count is therefore suspect too).
populationtablecorrected is loaded from files 'population1.txt' and 'population2.txt'. Dups are removed with a max.
'population1.txt' and 'population2.txt' are in:
Z:\Hubs\2017\clean data\Population
Their construction notes are on Hubs#Population_Data
