• Herd Immunity Applies to Guns as Well as Vaccinations

    February 4, 2015

    The recent measles outbreaks have sparked a national debate over vaccinations and the concept of “herd immunity.” The basic idea behind herd immunity is that “the vaccination of a significant portion of a population provides a measure of protection for individuals who have not developed immunity.”

    The concept of “herd immunity” applies to gun ownership and crime rates just as it does to vaccinations and infectious disease.

    Crime rates in Chicago dropped dramatically in 2014 after the state of Illinois allowed legal concealed carry.From the Washington Times:

    [T]he number of robberies that have led to arrests in Chicago has declined 20 percent from last year, according to police department statistics. Reports of burglary and motor vehicle theft are down 20 percent and 26 percent, respectively. In the first quarter, the city’s homicide rate was at a 56-year low.

    As Richard Pearson of the Illinois State Rifle Association observed:

    It isn’t any coincidence crime rates started to go down when concealed carry was permitted. Just the idea that the criminals don’t know who’s armed and who isn’t has a deterrence effect. … The police department hasn’t changed a single tactic — they haven’t announced a shift in policy or of course — and yet you have these incredible numbers.

    Richard Pearson estimated that 100,000 Illinois residents will have applied for concealed weapons permits in 2014 (out of a total population of 12 million). This works out to approximately 0.8% of the population.

    In other words, “the 1%” of concealed weapons permit holders in Illinois have created a measurable benefit for “the 99%.” Not a bad payoff!

    The Crime Prevention Research Center claims similar results nationally:

    In 10 states, more than 8 percent of adults hold concealed carry permits, and all are among the states with the lowest crime rates. Lott claims his group’s analysis shows that each one percentage point increase in the adult population holding permits brings a 1.4 percent drop in the murder rate.

    The medical theory of “herd immunity” posits that enough vaccinated individuals in a population can reduce the risk of contracting a disease — even for those who aren’t vaccinated. From the experience in Illinois and around the country, a relatively small number of armed people can similarly reduce the risk of crime — even for those who aren’t armed.

    So if you don’t own a gun but you are enjoying safer nights out on the town or sleeping more easily in your bed at night, give a little thanks to your neighbors who are gun owners. You’re the beneficiary of gun “herd immunity.”
