pic: ChiefDelphi Users per Capita: United States



This is a close-up look at the number of Registered Users of CD per capita in the United States. Check out the entire world here and a close-up of Canada here, as well as a higher-res version of the above picture here at my Flickr photostream.

I decided a little while ago that since there was a significant effort underway to create maps of FIRST teams around the world (http://www.chiefdelphi.com/forums/showthread.php?threadid=57354), there should also be maps of CD users. So I’ve been working on a little project in my spare time to create tallies of CD users in countries around the world, as well as in US states and Canadian provinces.

I used some custom macros and visual basic code in MS Excel to download username and location info from every user on CD, by starting with http://www.chiefdelphi.com/forums/member.php?u=0 (link returns an error) and increasing the final number by one to move to the next user. The last user I included in the maps was VexNerdVex (http://www.chiefdelphi.com/forums/member.php?u=20500), who joined CD today. It took about 4 hours for my automatic data-gatherer to wade throught those 20500 pages. Brandon, if you’re wondering why you just got 20500+ hits from the same machine over the course of the last day and a half, now you know!

Caution: All locations have been self-reported by ChiefDelphi users and therefore may contain some error beyond my control. For example, some users on CD apparently come from “cheap viagra pills” or “The Deep Corners of Planet Zantarh.” Needless to say, I could not use those results, and I recorded them instead as generic users, or in a more romantic sense, “citizens of the world.” Because it would be impossible to guess where those users really are located, I spread them out over the entire globe. That’s why, in the key below, the WHITE category starts at 0.057 users per million people. I used the same technique to create a generic category for users who entered “canada” or “usa.”

After getting all that user info, I had to massage the data semi-manually (using a few of my favorite Excel tricks!) until I had a tally-able and catalog-able product. I used a logarithmic function to break the categories into color groups suitable for coloring the map. I listed the key here:

ChiefDelphi Users per Million People
White: 0.057 - 0.08208
Dark Blue: 0.08209 - 0.2231
Blue: 0.2232 - 0.6065
Light Blue: 0.6066 - 1.648
Aqua: 1.649 - 4.481
Green: 4.482 - 12.18
Yellow: 12.19 - 33.11
Light Orange: 33.12 - 90.01
Dark Orange: 90.02 - 244.6
Red: 244.7 - 665.1

If you’re really interested, I can send or upload the Excel spreadsheets that I used to create these maps.

New Hampshire wins again!

I started using Google Analytics for chiefdelphi.com back on May 9th.

Some of Google’s regional stats for the US and Canada for May 9-31 are attached.

I love how St. Catharines has the second most visits for all of Canada, despite being a relatively small city, with only one team. (Not sure if these divisions include the surrounding areas, such as Niagara Falls and Fort Erie, which would bring the team total to three) Glad to see 1114’s ChiefDelphi obsession is showing through.

GO NH!!!

Wow, I’ve never seen a map that includes the Great Lakes as a portion of the adjacent states. Michigan sure looks ugly.

that’s pretty amazing.
one day, someone will have a map just like that but for every country that has participating FIRST teams :slight_smile:
only thing I disklike about the map is the colors used… for those colorblind folk, it is hard to depict where the yellow ends and the orange or dark orange or red begins :rolleyes:

Huh, I didn’t think about that. I originally tried to model the colors on a population density map (example: here), but I thought that it might be too hard to distinguish the colors, so I decided to use the whole rainbow. Truthfully, I’m not very happy with the way the colors came out myself. Oh well.

Nice map, I am proud to be in the orange…
