When the state's concealed handgun statute was approved 15 years ago, lawmakers argued it would help citizens defend themselves — but residents of low-income, largely Democratic nieghborhoods aren't applying for gun permits as often as those in wealthier, more-conservative areas, according to a Texas Tribune/San Antonio Express-News analysis.

In the two years since Barack Obama was elected president, many Texas gun owners — afraid of losing their Second Amendment rights — have stocked up on weapons and ammo. Texans have also sought a record number of concealed handgun licenses. Coincidence?
The Tribune analyzed Texas Department of Public Safety data on concealed handgun license issuance during 2009, creating thematic maps that show a county-by-county breakdown of the total number of licenses issued and the per-capita rate. The latter figure is a more accurate measure for the proportion of residents who received licenses. Darker colors represent higher totals and rates.
In a pattern that's playing out in San Antonio and other major metro areas in Texas, residents in low-income neighborhoods aren't taking advantage of the state's concealed-carry law as often as residents living in wealthier, more conservative areas.

A representative for the Texas Legislative Council, which helps lawmakers research and draft bills, won't speculate on why proposed and passed legislation has risen sharply in the last two decades. But it's one reason the agency has expanded its legal division over the years, she says.
Legislative filings increased in the Texas House and Senate by 70 percent from 1991 to 2009, records show, and the number of bills and resolutions passed by both chambers climbed at a higher rate. Resolutions alone numbered about 4,000 last session, or more than half of all legislation. Explore our interactive graphics.
This interactive chart visualizes the roughly 90,000 bills and resolutions introduced by members of the Texas House and Texas Senate since 1991. Click through the tabs to see visualizations of legislation that introduced, passed by both chambers or vetoed by governors Ann Richards, George W. Bush and Rick Perry.

Using data compiled by the Austin American-Statesman, we've produced county-by-county maps visualizing Texas Lottery sales by game type. A higher percentage of lottery revenue in Hill County counties, for example, came from Lotto sales in 2009. Many counties in West Texas, however, appear to prefer instant scratch-off tickets.
Earlier this week, the Austin American-Statesman published an interesting series about the Texas Lottery. We mapped the data, which the paper's editors graciously released, to visualize fiscal year 2009 sales and residents' income characteristics by zip code.
