The Low Degree of Violence in U.S. - Mexican Border Cities

U.S.-Mexican border cities have been experiencing a historically low rate of violent crimes, at least through 2016, the most recent year with statistics available from the FBI's Uniform Crime Reports.

In my previous analyses, I looked at the recent rate of violent crimes versus the peak year. In that study I used statistics through 2014 which were the most recent numbers compiled into the city tables. Since then I discovered that the 2015 and 2016 annual reports included information for major cities.

So: this post includes the years 2015 and 2016 and rather than look at single year peaks, I compared the peak five consecutive years to the most recent five consecutive years. Being a different analysis, and less reliant on single year peaks, the numbers come out a bit differently, and are less prone to error.

To be clear: these data, the most recent available, represent crime through the end of the Obama administration and this is not a commentary on subsequent changes.

The five cities chosen were those U.S. cities that had over 100,000 in population and which border Mexico: Brownsville, McAllen, Laredo, El Paso, all in Texas, and San Diego, in California. The statistics used were total violent crime rates, murder rates and the rate of rapes, available in the FBI city tables beginning with the year 1985.

Of the cities/measurements, all 15 show lower crime rates in recent years: in most cases, dramatically lower.

Brownsville Violent Crimes. Down by 76.5%
" " Murders. Down by 88.3%
" " Rape. Down by 49.1%

McAllen Violent Crimes. Down by 83.2%
" " Murders. Down by 67.6%
" " Rape. Down by 68.8%
 
Laredo Violent Crimes. Down by 37.7%
" " Murders. Down by 75.7%
" " Rape. Down by 6.1%

While all other city statistics show a 30% drop or more, rapes in Laredo had a negligible drop.

El Paso Violent Crimes. Down by 64.0%
" " Murders. Down by 68.1%
" " Rape. Down by 33.7%


San Diego Violent Crimes. Down by 66.7%
" " Murders. Down by 76.9%
" " Rape. Down by 32.8%

United States. Violent Crimes. Down by 49.3%
" " Murders. Down by 48.6%
" " Rape. Down by 33.7%

Four out of five of the border cities had violent crimes drop at a greater rate than the U.S. as a whole. Five out of five had murder drop at a greater (much greater) rate than the U.S. as a whole. Three out of five of the cities did equal or better in improving their rape statistics. (El Paso tied, San Diego less than one percent behind, and Laredo not doing well.) In total, according to the metrics, the border cities outperformed the U.S. as a whole in 11 out of 15 measures, with one tie.

So, here are the graphs.

Brownsville.

The Low Crime Rates in U.S. Cities along the Mexican Border.


In a previous post, I looked at the rates of violent crimes in border states. Those states bordering Mexico have had a huge drop in violent crime over the past 20-some years, from the time at which violent crime peaked in the United States in 1992 through 2013, the latter year being the latest data available at the time of my analysis.

The four Mexican border states and the drop in their rates of violent crimes.

California:  -63.3%
Arizona: -40.8%
New Mexico: -35.6%
Texas: -50.1%

These findings are based on the the Uniform Crime Reporting statistics. The UCR stats have been assembled by the FBI going back to the 1930s. In recent years the FBI has put their data online allowing analyses of crime rates according to standardized criteria. The annual data are, for the most part, nine months behind with the year 2016 information appearing at the end of September, 2017. In 2017, the Trump administration decided to provide much less detailed information (70% fewer tables) in comparison to previous years and this will affect future assessments.

Looking at Border Cities.

Alright, states are large and changes in crime in Northern California might not reflect activity closer to the border. So I decided to examine crime rates in another way. The FBI also collects crime statistics for cities. There are five cities on the United States-Mexico border which have a population of over 100,000.

Let's get out of the way two problems with the city statistics. First of all, as of now, the statistics available for these cities is through 2014. Secondly, in 2014, four out of five of these cities switched to the new rape definition and did not report the legacy definition numbers. This leads to an artificial bump in both rape and, to a lesser degree, total violent crime statistics for the final year of this analysis. Using national statistics over a period of four years where both definitions are used, the new definition shows a 38.1% higher incidence of rape.This figure should be reliable represents over 400,000 rapes reported with both definitions.

Violent Crime in Border Cities.

I came to this analysis with an open mind. Would I find an increase in violence? On the one hand, national violence statistics have sharply declined since the nineties. On the other hand, the city of Matamoros, on the Mexican side across the border from Brownsville, gets its name from Mata (Spanish for kill) and Moros (Moors). It did have a death cult causing havoc back in the eighties. So, is violence along the border a spooky fact or spooky myth?

The United States as a Whole.

Violent crime in the United States peaked in 1992. Percent down from peak: -51.8%.

Murders. Peaked: 1986*. Percent down from peak: -54.1%.
Rape. Peaked: 1992. Percent down from peak: -38.3%.

A Tour of the Five Border Cities with 100,000 or more in population.



Brownsville is on the Texas-Mexican border near the Gulf of Mexico. In 2014 it had a population of 183,433.
Violent crimes. Peaked: 1988. Percent down from peak: -77.3%.
    Adjusting for legacy definition of rape: -78.5%.
Murders. Peaked: 1986. Percent down from peak: -82.9%.
Rape. Peaked: 2006. Percent down from peak: -30.0%.
    Adjusting for legacy definition: -49.3%

Conclusion: Brownsville was a dangerous place that has greatly decreased its violence. A concerning recent uptick in rape, but still half of its peak.

McAllen.

Moseying up along the Rio Grande, 60 miles to the northwest, we come to the city of McAllen. In 2014 it had a population of 138,122.

Violent crimes. Peaked: 1994. Percent down from peak: -83.2%.
    Adjusting for legacy rape definition: -84.7%
Murders. Peaked: 1986. Percent down from peak: -56.6%.
Rape. Peaked: 2006. Percent down from peak: -75.7%.
    Adjusting for legacy definition: -82.4%.

Conclusion: McAllen, also, is a much safer place as is shown by its graphs.

Laredo.

Another three hours up the Rio Grande and you come to the streets of Laredo, once the capital of the Republic of the Rio Grande. In 2014, it had a population of 250,994.

Violent crimes. Peaked: 1989. Percent down from peak: -57.0%.
    Adjusting for legacy rape definition: -58.2%
Murders. Peaked: 1986. Percent down from peak: -68.2%.
Rape. Peaked: 2006. Percent down from peak: -11.9%.
    Adjusting for legacy: -36.2%.

The results are not quite as dramatic as they are for Brownsville and McAllen, but Laredo has also lowered its crime rate. This city had one high year (1989) in overall violent crime and if the comparisons are made to its established high in the 1990s, the decline is closer to a 40% drop. The rape statistics show a marked increase during the 1990s (prior under-reporting?).

El Paso.

The largest city along the Texas-Mexico border is El Paso. In 2014, it had a population of 680,273.

Violent crimes. Peaked: 1993. Percent down from peak: -64.4%.
    Adjusting for legacy rape definition: -65.6%
Murders. Peaked: 1986. Percent down from peak: -67.4%.
Rape. Peaked: 2006. Percent down from peak: -3.1%.
    Adjusting for legacy: -29.9%

El Paso has dramatically reduced its violent crime and murder rates. As with Laredo, much of the recent higher (but not highest) rate of rape is due to the revised definition.

San Diego, California has more people than the other border cities combined: in 2014, 1,368,960. They have only reported using the legacy rape definition, so there is no distinction necessary when making comparisons.

Violent crimes. Peaked: 1992. Percent down from peak: -70.3%.
Murders. Peaked: 1991. Percent down from peak: -84.4%.
Rape. Peaked: 1992. Percent down from peak: -35.6%.

San Diego has shown a remarkable decrease in violent crime over the past two-plus decades.


Overall Conclusions.

Each of the border cities have shown a drop in violent crime and murder rate greater than that of the nation as a whole. While the U.S. as a whole saw a greater than 50% drop in the rate of violent crimes and murders, rapes only dropped by -38%. Each of the border cities has a lower rate of rape, with McAllen showing an -82.4% decline, and El Paso showing the least, with a-29.9% decline.

In Perspective.

In Nazi Germany, Jews were labelled as criminals and rapists. Typical is a speech of Goebbels wherein he said he does not deny Jews are humans. Neither did he deny the humanness "of murder[er]s, child rapists, thieves and pimps."

Dylan Roof, who gunned down nine African-Americans in a South Carolina church, declared the day before his attack: "you rape our women and you’re taking over our country. And you have to go."

The local head of the Ku Klux Klan clarified this sentiment: "A better target for him would have been these gang-bangers, running around rapping, raping, and stealing." [Both statements referenced here.]

Birth of a Presidency.

The same week as the comment quoted immediately above, Donald Trump, when making his speech announcing his bid for the presidency, said:

"When Mexico sends its people, they're not sending their best — they're not sending you. They’re not sending you. They're sending people that have lots of problems and they're bringing those problems with us. They're bringing drugs. They're bringing crime. They're rapists. And some, I assume, are good people."


These hateful fantasies have no basis in reality.

A Couple of Statistical Notes.

"Down from peak" is potentially a problematic statistic. It can present artifacts as findings. It works great to define what's going on when you are currently at the peak, or when the peak and trough represent consistent findings. "Down from peak" also does address whether peak violence is occurring. To account for some of its potential bias, the graphs of each year reported in the database are presented.

Legacy Rape. Rape was redefined in 2013 to include more than just forcible rape. In most cases, the legacy definition numbers are included using the older definition which allows for direct comparisons. Overall, the legacy rates compared to the newly defined rates (overall, U.S., per 100,000):

           New  Old (Legacy)
2013  35.9   25.9
2014  37.0   26.6
2015  39.3   28.4
2016  40.4   29.6

Over those four years the revised definition has a 38.1% higher rate than the legacy definition.

The U.S. had its absolute peak in murders in 1980. I chose the year 1986 to be in line with information available from the cities, from 1985 to 2014.

The UCR statistical data tool has been out of service (or just not responsive to my attempts to access it) for about a week and this prevented me from following up on some of the above questions.  Fortunately, I had already downloaded the most relevant data. I hope to write a follow-up piece, soon.
