Hello everybody, a little update on the spreadsheet. The link in the OP now just directs you to another spreadsheet. I can't update the OP, so this seemed to be the best solution. This "new" spreadsheet is a stop gap while I slowly plug away on a dedicated website with some neat features to compare airlines, city data etc.
There is a couple reasons for the change, the first being that I wanted to get away from the basic public spreadsheet because I had people requesting access to edit it all the time. It's now a published sheet and there is a link at the top to a form to provide information. You can still PM me if you wish to do it that way. This format is also a little bit cleaner.
Second, all COL data is now based on census.gov rather than third party sites. I've regularly had people dispute the information for apartment costs etc, so I went this route to be as "official" as possible. There is an explanation for what those values represent at the bottom of the sheet. You can click on the HDQ city link to see the full census data for that city, which is pretty neat.
Regarding the form to provide info, I want to make it clear that I have not, do not, and will not reveal your identity, username, email, etc to anybody (this is regardless of how you give me info, whether it be by forum PM, this google form, direct email, or some form of social media). The bottom line is I get all my info from Casper the ghost, he's a cool guy..err..ghost. There is an upload option to upload pay scale documents/ images, supporting documents etc that help me verify the information being given, as well as helping me keep it updated over time. It's not mandatory, but very appreciated.
Thanks again to everybody for providing information and making this spreadsheet possible over the last few years.
