Ever notice how noisy a standard choropleth map can look?

Bivariate proportional symbol maps--using symbols that vary by both size and color--can convey all the same info that a choropleth map does but in better proportions, in better locations, and with much less noise...

@fmaddenNBA It also underscores the massive importance of 3P% variance. The whole sad story starts with a series loss where the Heat went 45% from 3 with nearly every player greatly exceeding their career %.

Jrue, a career 37%, had the most 3PA of anyone in the series... and shot 29%.

@lymanstoneky @mnolangray But the book is *also* very much about how Chicago usurped St Louis’ place, directly addressing the vision St Louis had for itself and how and why it failed

@_fat_ugly_rat_ We'd hear A LOT fewer complaints about the EC's imbalance relative to population if we solved its much bigger problem: winner-take-all elector assignment... which is nowhere in the Constitution. (It's only the Senate where the Constitution *really* hammers the big populations.)

@kennethskates @statmuse Best net rating in the reg season last year!

(> 600 min played, among trios who are still intact... Hartenstein/Hart/Brunson were slightly higher)

@maggiekb1 Fayette State Park. It's worth the out-of-the-way trip down the Garden Peninsula.

@nathanmarzion Around half, down a bit from recent years. Too many stretches where it felt like we were set up for disappointment and weren't learning much due to injured players, weird/new coaching, and generally inconsistent play.

@marcfbellemare For the average CBSA population, we have separate variables...

[Jonathan Schroeder @j_p_schroeder]

@marcfbellemare DENSITY currently uses:
- 2000 densities for 2000 decennial samples
- 2010 densities for 2005-2021 ACS samples
- 2020 densities for 2022 ACS sample (just released today!)
...

Ever notice how noisy a standard choropleth map can look?

Bivariate proportional symbol maps--using symbols that vary by both size and color--can convey all the same info that a choropleth map does but in better proportions, in better locations, and with much less noise...

New @ipums blog post:
Bivariate Proportional Symbol Maps, Part 2

Defaults get you only so far. ArcGIS Pro's defaults could give you the map on the left. I step through how to improve on this, along w/ several other design tips & instructions...

I share a few examples to demonstrate the advantages of bivariate proportional symbol maps in a new @ipums blog post: https://t.co/hYF102N5tc

I'll also share a follow-up post soon with some design tips and instructions.

@dhmontgomery @xkcd Also, importantly, I detect a subtle plea for Wisconsin to absorb Upper Michigan.
