Assessing the Validity of Online Sources

This is a fabulous map---but is the statement true?

Courtney Burns's insight:

When we first looked at this picture in class there was no way that I thought this map could be true. We are warned all the time to be careful what we look at on the internet, because for the most part a lot of the information is not true. When we looked at this photo in class we zoomed in on the area in the circle and first determined what was included  in that circle. Once we were able to detrmine what cities were within that circle we were then able to look up the population in each of those cities. We added up the total of each city to get the total population of the places within the circle. Then we researched the total population of the world. Once we were able to find this we subtracted the population from within the circle from the total population, and what we were left with was smaller than the total population within the circle. Which means that the map was true. I was shocked. There was no way that I thought this was true. What was interesting to me was the process we went through to determine that this map was even true. We had to detrmine the area we were working with and then research the information to get a solution. I think you learn a lot just by this simple picture. This map happened to be true however there are many picture listed under this map that are untrue that we are faced with all the time, that if we took the time to research we woudl realize are silly pictures. Just by researching information about a picutre like this can teach us a lot about a place.

After analyzing this map and looking at the busiest cities and countries in the world I believe this statement to be true. China a giant and very populated country, India is also within the top ten and so is Japan. Once all these have been looked at you can clearly tell that this area of the world is easily the most populated. Many of the other countries and nations have large swaths of land that are very lightly populated. This is a robust area of the world and in some cases the most expansive.

It surprises me how many people live in just that one circle! it is hard to believe or probably explain to someone that with all the other space in the world, that the circles region has more people in it than what is not circled. Although, it could be validated by more reliable or more sources, because with the world that we live in now, numbers can easily be forged. I do believe though that 51% of the world's population does live here.

This is perhaps the most intriguing map I've been able to analyze. Could it be possible that more people live in that circle than out of it? The world is HUGE and to think the majority of the population resides here, is truly incredible. India, has a huge population living in there for such a small area. Currently, India has over 1 billion people living there making it the second most populous country before China with 1.3 billion. China has a bigger surface area than India and it is interesting to know how these areas compare. The important issue with India is the fact that, with so many people, there is a lack of housing and sanitation unavailable to provide to so many people. The facts are giving that India suffers from overpopulation, clearly, this image has to be true.

Local Life Expectancies

Local Life Expectancies | Georgraphy World News | Scoop.it

We often talk about life expectancy data at the national level; this simplification has a great deal of utility but obscures regional distinctions within a country.  Some counties in the United States have life expectancies on par with Japan (84), while the worst off counties are more similar to Indonesia (69).  Even more startling, in 661 counties, life expectancy stopped dead or went backwards for women since 1999.  This is a dramatic look at the importance of scale within any geographic analysis to arrive at reasonable conclusions.  So let's start looking at local demographic data instead of just nationally aggregated data.  For more on this press release, see:  http://www.healthmetricsandevaluation.org/news-events/news-release/girls-born-2009-will-live-shorter-lives-their-mothers-hundreds-us-counties

Courtney Burns's insight:

Typically when I think about the average life expectancy today I think of how it has increased over the years. However I never thought of looking at it broken down into gender and area. When it is broken down the life expectancy of women is not increasing like it used too and in some places is even going down. In the graph it says that 54,000 women die every year because of excess salt. That stat is crazy! Even though that may not be a huge percentage of our population. It is something that can be monitored more and prevented. It would be interesting to see why people live longer in certain areas. What is it about specific areas that these people are living the longest? Even though the average life expectancy as a whole as increased I think we should look more into the decrease of life expectancy of women and why men's life expectancy's are increasing so much in comparison to women.

I wonder what the link between male longevity and Iowa males is? Perhaps the connection the land -physical work and local food.

When I hear about life expectancy the first thought that pops into my head is that the U.S. must have a great life expectancy considering all the medicines and treatments we have available. But when I read that since such a large numbers of counties have seen woman life expectancy stop dead or go backwards since 1999, I was absolutely shocked! Why was the life expectancy of women's dropping in so many more counties, an why weren't the men's life expectancy also dropping?And why is it that women live the longest in North Dakota and men in Iowa? Reading further, we see that a large percentage of women dying each year is because of excess salt and a large percentage of men dying each year is because of smoking. Both of these things can be prevented, but yet we still see many Americans do them. One good thing we learn from this is that African American males life expectancy has improved greatly over the past two decades. I would be interested to find out why that is, and if it could help the rest of the population also increase their life expectancy.

Life expectancies do vary.  I know that one of my grandmothers died around when she was 60, and my other grandfather just passed away at age 84.  I am 23 years old, and the difference between their death ages is close to 24; one lived a whole "one of my current lifetimes" more than the other, which is strange to think about.  All that I've ever known can fit into the time that one lived longer than the other.  Life is transient, but just that.  The "death expectancy" is that everyone will die, absolutely.  No exceptions.  I was given a paper from a friend in high school, one of those motivational readings, on "What will you do with your 'dash'?"  It referred to gravestones, ie) someone lived from 1927-2012.  The two dates aren't really what matter, but the 'dash' in between, and how we choose to spend our lives is the true part that really matters!  So know what to expect, on average and based on where you are from, and be prepared for some differences from that average, but make your 'dash' truly matter! After all, it's the most we can do...
