The best measure depends on the question asked. At present, we have comparators that give you seven answers for the United States (from 1774 on), five for the United Kingdom (from 1270 on), five for Australia (from 1828 on). These dates are determined by the limits of available data.
"Geography. It lets you study the world. No, really, THE WORLD. Think about that. What other subject deals with rocks? Moving continents? AND climate? Diffusion of plants and animals? Water quality? Now, what if you add some human systems--do the other sciences let you relate the earth to economic or political systems? And culture--food, religion, music, housing, or language? How about urban systems and settlement forms? Past, present, and future, anywhere in the world? And how many subject areas let you look at something from a scientific, social-scientific, humanistic, AND artistic perspective? Yeah, I said artistic--I like to illustrate my findings with a nice map.
Tell me all about global studies or environmental science if you'd like--they're alright too. But NOTHING lets you see the world like geography does."
"About 10,000 years ago, hunter-gatherers, aided by rudimentary agriculture, moved to semi-permanent villages and never looked back. With further developments came food surpluses, leading to commerce, specialization and, many years later with the Industrial Revolution, the modern city. Vance Kite plots our urban past and how we can expect future cities to adapt to our growing populations."
"I have had a number of requests for copies of GIS in the History Classroom in a format other than iBooks. I have just completed an internet version of the book that works on Safari, Firefox, Chrome, and Internet Explorer."
