Demography is Destiny - Part One




Our last three posts have been about Charlie Hebdo, terrorism and Islamic immigration. There has been excellent response by readers. The present post is also related to those topics.


The title of this piece is usually attributed to Auguste Comte, the father of Sociology, and I want to show  how   true it is.

Two of the things  which the media never let us forget  are:
(1)   terrorism/crime/violence/war and
(2) immigration.
These  two issues  are related, as in the Charlie Hebdo case, because some of the violence is committed  by Muslim immigrants to places like France.

Western societies, foremost among them the United States, are in a never-ending search for the explanations and solutions to  this dual problem, always  trying to implement a variety of  policies. Experts are  pulling their hair out trying to explain crime and violence. The explanations and  policies range from various criminological fads, all the way to war.

For example, criminologists disagree as  to why the US crime rate is down so very sharply. Sometimes the criminal justice system feels that  more punishment and more law enforcement are the answer, so we build more prisons and we  hire more cops. At other times, sociologists advocate more rehabilitation and more help with mental health, so we go the other way. Theories such as James Q. Wilson’s broken windows idea come and go. Guns are always a hot topic.  And of course, to combat and protect against international violence, we engage in multiple wars, and we  spend ourselves into bankruptcy with   Homeland Security. This never-ending quest for explanations and for policies that will reduce criminal violence  has been going on for centuries.

But let me suggest something else, something based on Comte’s axiom that demography is destiny:
There is no factor that correlates more strongly with criminal violence than AGE. No explanation and no amount of dickering with policies sheds as much light on the issue as  the recognition of one simple, fundamental fact: namely that criminal violence is something that is done by YOUNG MEN. Period.

To see the role of demography, let’s look at the two afore-mentioned and related issues:

1) Crime, violence, war: There is  a sense, nowadays, that the world is rife with conflict and violence.
We live in a near-permanent state of low-level warfare, terrorism flares up periodically, and  crime ranges from low  levels  in places like Northern Europe and Japan,  medium amounts  in the United States, all the way to disastrous levels in some Latin American countries and in failed states such as Somalia.

A caveat: worldwide  violence and war  are down, not up. Nervosity about them are up, due to the news media, the social media and  the Internet.  But this is a perception thing. It is aided and abetted  by the non-stop chatter about  terrorism.   In fact,  the historical trajectory has been a sharp downward trend in worldwide violence of all sorts. (See for example Steven Pinker’s The Better Angels of Our Nature) This  is true for both  the long-term and for the short-term, both for large-scale, organized warfare,  and for  private individual criminal violence.

Fluctuations in violence over TIME and variations by PLACE   are  precisely what  “demography is destiny” explains so well.

Take the declining American crime rate. Our national murder rate has gone down  from 10.2 per 100,000 in 1980 to 4.4 in 2013. That is a 57% decline over 33 years. In 1990, there were 2,245 murders in New York City. Last year there were 328. That’s a decline of 85% (!) over 24 years.

Has the number of guns declined over this period of time? Absolutely not. The contrary. Don’t misunderstand me: I strongly support gun control, and I still believe that the fewer fire arms there are  in circulation, the better. However, the relationship between gun ownership and the crime rate  is complicated, and one to which I cannot do justice here.

Are New York police  commissioner Bratton’s policies responsible? Who knows. Probably not, since other cities have experienced similar reductions in crime.

But one thing is clear: Since 1990, US life expectancy has gone up from 75.3 years  to 78.9 years.  Americans’ median age was 32.9 years in 1990 and it rose to 37.7 years by 2014 - an increase of nearly five years.

Nothing correlates more strongly with crime than age. Not gun ownership, not rates of incarceration, not the number of cops on the street, not economic conditions. Ninety-eight percent   of all the index crimes tabulated by the FBI  are committed by people under fifty.  Two percent by people over fifty. As America ages, its crime rate goes down. Simple.

Now take a look at the world. Table One, cleverly combining two different sources,  gives you a sample of 40 selected countries of interest, half of them with high murder rates and half of them low. I deliberately excluded  city states like Monaco and Hong Kong (Countries by Median Age;  Countries and Continents Murder Rates)

Table One shows clearly that  the younger a country’s population is, the higher its murder rate tends to be. The strong correlation is evident from mere visual inspection. No Chi Square needed here.

Table Two sums up the relationship between age and murder rates in a more global way:

             Table Two: Relationship between Age and Murder Rates, by Continents/Regions

Median Age
High Murder Rate
Medium Murder Rate
Low Murder Rate
Young
Africa
Latin America
Caribbean


Medium

Asia
Middle East

Old


Europe
North America
Australasia

So you see, explanations such as gun ownership, law enforcement, political strife and poverty are not nearly as helpful as the one crucial variable of  AGE!
Remember Michael Moore’s great film, Bowling for Columbine? Canada has as many fire arms per capita  as the US.  So do  the Swiss and the Israelis. Yet those countries’ murder rates are much lower than  ours. Similarly, within the US,  states with stricter gun laws (New York, the District of Columbia, etc.)  do not  necessarily have lower murder rates.

Clearly, crime and violence are multi-causal, like most social phenomena. By no means do I intend to reduce my explanation of violence to a single independent variable. My intent today has been to focus on something that is perhaps somewhat overlooked - age - and also to offer a bit of a lesson  in humility: Human intervention through social policies may not be as consequential as natural processes over which we have little control:  Demography is destiny. leave comment here
