71% of the pit bull fatalities have occurred in the past 10 years; 42% in the past four years; 24% in the past two years.

Of course, as pit bulls increase in number, the maiming and killings increase.

Yes. As the number of the various breeds lumped in as 'pit bulls' bred by backyard breeders looking for aggressiveness and size increase in number, and the number of owners who don't socialize their dogs and encourage them to be aggressive increase, the maiming and killings by at least some of the breeds that are deemed 'pit bulls' increase.

There are no statistics to show that each of the various breeds lumped in as 'pit bulls' have shown an increase in maiming and killing.

I'll wager there has been a dramatic increased in the number of deaths caused by American Pit Bull Terriers, but not by American Bull Terriers. Both are considered 'pit bulls.'
