Looking Back: Facts from the last English Century.

I was reading through 'A Century of Change: Trends in UK statistics since 1900' available online at the UK government's website. A few things seemed interesting; take from it what you will.
 

We pay more at Retail and the buying power of the £ has decreased. But then we earn more.

Despite many more cars, deaths on the roads have decreased.

We haven't learned not to go to war.

There is either more crime, or the Police have got better at catching criminals. Probably both.

More people own the house they live in. This is due to 'credit' from mortgage arrangements and the Right to Buy from the 80s.

People used to be leaving England; now they are arriving. Overall population has continued to increase, but birth rates are down from about 3.5 children per completed family at the start of the Century to 1.7 at its end.

Cancer and circulatory deaths are more common. Why?
