Quick @Stata tip: use the "coeflegend" option in a regression to display the name Stata uses for each coefficient. reg price mpg i.foreign##i.rep78, coeflegend

The changing relationship between Democratic vote share and 1) the percentage of county with at least a Bachelor's degree 2) median income of county.

Over the past couple decades, Democratic support has grown in more college-educated and higher-income counties, a shift away from its traditional blue-collar strongholds. h/t ‪@shanegoldmacher.bsky.social‬

The relationship between a county’s Democratic vote share (in the 2024 election) and its share of college-educated residents.

Percent (age 25+) with a Ph.D. On a personal note, I have lived in two of the top 25 (#3 Tompkins County, NY and now #22 Oktibbeha County, MS). Top 5: 1. Los Alamos, NM (18%); 2. Lexington City, VA (12%); 3. Tompkins County, NY (12%); 4. Orange County, NC (9%); 5. Charlottesville city, VA (8%).

Our baby boy is here! That makes four kids under six - wish us luck!

Falling fertility.

Here are some ways the world has gotten better.

When in the day are babies born?

Number of births per day, 1994-2014.

Average number of US births by day of the year.

Average number of births by day of the week.

That was unexpected - Elon Musk retweeted my graph.

There were more Latter-day Saint convert baptisms last year than any year since 1997.

Quick Stata tip: "set sortseed" sets the seed for sorting tie breakers for things like "sort", "gsort", and "kmatch, wor." It can be useful when creating replicable code.

I plotted a histogram of the distances of 701 of my runs, and apparently I like to stop right after hitting whole numbers/5k/10k.

The free Chrome plugin "Advanced Profanity Filter" is an easy and effective way to remove profanity/language from TV shows and movies. It works by recognizing words in closed captioning. Siftbooks, a subscription service (that I haven't tried), filters out language and content on Audible books.

Distance to nearest NFL team.

What are your favorite books of all time?

Distance to nearest Bass Pro Shops - probably my most beautiful map ever

Distance to the nearest IKEA.

Distance to the nearest R1 university (i.e., "Doctoral Universities – Very high research activity" as classified by the 2021 Carnegie Classification of Institutions of Higher Education).

Quick Stata tip: reghdfejl is much faster than reghdfe. ssc install julia net install reghdfejl, replace from(raw.github.com/droodman/reg...) webuse hdfe, clear tempfile a save `a' *N=10M: forv i=1/9 { append using `a' } areg y x, a(id a1 a2) reghdfe y x, a(id a1 a2) reghdfejl y x, a(id a1 a2)

Quick Stata tip: keep if inlist(state, "AL", "AK", "AZ") is the same as: keep if state=="AL" | state=="AK" | state=="AZ" And: keep if inrange(distance, 10, 91) is the same as: keep if distance>=10 & distance<=91

Quick Stata tip: use "recol" to shorten the column width of variables in the Data Editor. This is useful for really long strings. ssc install recol sysuse census, clear replace state = "ABCDEFGASDFASDFSADF" in 1 recol state, maxwidth(7) compress

Distance to nearest National Park.

Quick Stata tip: to rename all variables so that they are lower case: rename *, lower

Quick Stata tip: To quickly see how many observations of each variable are missing, use mdesc: ssc install mdesc sysuse lifeexp, clear mdesc

Quick Stata tip: If you want to look at a one-way frequency table of a variable, "fre" displays both values and labels at the same time, while "tabulate" does not. To use fre: ssc install fre sysuse auto2, clear tab foreign fre foreign
