The variance of age-sex from place to place

One of the geographical features of the social landscape that varies across space is that of the age and sex of a population. As the Spatialworlds posting titled, 'Spaced out! Variance across space ' pointed out, what fascinates the geography is that no two places are the same and in turn the geograper frequently asks; "why is it so?" - to hypothesise why the variance occurs. This ESRI geo-enrichment platform is a great resource for students to identiy age-sex variance across space (albeit only the US and Canada) and to hypothesis why the variance may occur. An amazing resource for the classroom at 

The ESRI Infographic widget requests GeoEnrichment data of a given location, and visualises the results in a Infographics consisting of properly formatted charts. This particular sample allows users to click any location on the map and returns the GeoEnrichment data (an age pyramid) of a 1-mile ring buffer area.

A previous Spatialworlds posting showcased an excellent country age-sex visualisation but this site enables us, for a least two countries, to drill down further to a specific place and to see the age-sex composition on a local scale. Students can then ask the; "why is it so?" questions. 

To explore this interactive map of the United States and Canada, just click on any neighbourhood to see the local population age-sex structure and compare that to the national, state or county data?  This is a fantastic resource that lets you and your students explore the data AND ask spatial questions.

A South Australian interactive resource on housing stress

Discover your suburb using InDaily’s interactive map below.
InDaily used data from the latest Australian Bureau of Statistics census (2011) to rank South Australia’s 821 suburbs by housing stress, median weekly household income and population.
The results demonstrate the local impact of a wider housing affordability crisis in Australia.
Adelaide, as well as every other major housing market in Australia, was rated severely unaffordable by this year’s Demographia affordability survey.
No Australian housing market, large or small, was ranked affordable or even moderately unaffordable by the survey. A Federal Senate inquiry into housing affordability is currently underway, and due to report its findings on November 27.
