Half the World Lives on 1% of Its Land, Mapped

Half the World Lives on 1% of Its Land, Mapped | STEM Connections |

"Data viz extraordinaire Max Galka created this map using NASA’s gridded population data, which counts the global population within each nine-square-mile patch of Earth, instead of within each each district, state, or country border. Out of the 28 million total cells, the ones with a population over 8,000 are colored in yellow."

Great simple map of world population.  Scroll down and look at the U.S.  It reflects the global trend.  This also has political implications, as evidenced by voting patterns in the 2012 presidential election.  Elections are dependent upon votes, which come from people, which are primarily clustered in cities.  Election campaigns would use this data to plan their schedules as to where to focus their campaigning efforts.  For the folks in Wyoming, they rarely see candidates other than during the primaries.  And these world populationclusters have been relatively consistent historically, particularly in south and east Asia.  Northern India has serious carrying capacity challenges. Notice the clusters along the Nile- evidence of arable land.

Fantastic visualization!

Geeky-cool stuff! Thanks to Jim Lerman.

How Suburban Are Big American Cities?

How Suburban Are Big American Cities? | STEM Connections |

"What, exactly, is a city? Technically, cities are legal designations that, under state laws, have specific public powers and functions. But many of the largest American cities — especially in the South and West — don’t feel like cities, at least not in the high-rise-and-subways, 'Sesame Street' sense. Large swaths of many big cities are residential neighborhoods of single-family homes, as car-dependent as any suburb.

Cities like Austin and Fort Worth in Texas and Charlotte, North Carolina, are big and growing quickly, but largely suburban. According to Census Bureau data released Thursday, the population of the country’s biggest cities (the 34 with at least 500,000 residents) grew 0.99 percent in 2014 — versus 0.88 percent for all metropolitan areas and 0.75 percent for the U.S. overall. But city growth isn’t the same as urban growth. Three cities of the largest 10 are more suburban than urban, based on our analysis of how people describe the neighborhoods where they live."

This article accurately depicts the difference between a normal city 50 years ago and a city today, as well as the continuing spread of suburbanization. For example, Austin, the capital of texas, a hustling, bustling always busy area, is predominantly suburban. As cities and countries continue to advance and develop and its citizens become more successful and family oriented, suburban homes for families will become more needed than something smaller, like condos or studio apartments. As the needs of the cities change, the structure of the city changes as well. This applies to our final unit of APHUG: Cities and Urban Land Use.

Canada is a huge country. Most of it is unfit for human habitation.

"The area below the red line includes most of Nova Scotia, in Canada's east, but most of the population comes from the area a little farther west, in a sliver of Quebec and a densely populated stretch of Ontario near the Great Lakes."

Admitted, the web Mercator projection of this map distorts the far northern territories of Canada, but still it hammers home some fascinating truths about Canada's population distribution.  Land-wise, Canada one of the world's biggest countries, but population-wise, most of it is quite barren.  What geographic factors explain the population concentration and distribution in Canada?

Over the years, ISS astronauts have had a rare opportunity to witness climate change on Earth from space.

A great illustation of the changes to the environment as a result of increasing technology and population. Plays for 1minute 30.

A short but fascinating illustration of the rapid changes to areas of teh Earth, observed by astronauts since 2000. Plays for 1 minute 30.

This is a great resource for some of our science classes. It is an interesting presentation of the changes that we are making over time.
