California's Population in 2007

For this assignment I decided to construct three different maps displaying California's populationi in three different ways. For my first map I organized and displayed population according to zip codes. I decided to omit border outlines for each zip code for two main reasons. The first reason was that in densely populated areas with many zip codes having small areas, such as in Los Angeles and the San Francisco Bay Area, it made it difficult to read the map for the boarder lines were too close together and took away from the overall color of the zipcode representing population size and thus was hard to read. The second reason was that it made the map feel very rigid with strict boundaries which isn't the case with zipcodes. Thus by omitting zipcode boundary lines there is a flow to the map showing the distribution of California's population. This map clearly demonstrates that California's largest populations are concentrated in the San Francisco Bay Area, the Central Valley, and along Southern California's coast from Santa Barbara to San Diego.
My second map displays population by county. This map shows population density to a degree, however, the map displaying population by zipcode does a better job of showing areas with higher populations. Nonetheless this second map is consistent with displaying areas with larger populations such as in the Bay Area and Southern California. My last map displays California cities which have the largest populations. This map allows for comparison between the different city sizes and their populations relative to one another. I think that alone this last map is not the best representation of California's population, however, used in addition to the map of population by county, it add more detail and insight into the distribution of population in California.

Election 2008

The first map that is displayed is a replica of a New York Times map of the 2008 United States Presidential Election, followed by a map I made making improvements to the original. I did not feel the need to make very many changes due to the fact that I think the original map is quite clear in conveying its message. My first improvement, however, was brightening up the red and blue colors from their originally muted shades in order to emphasize the contrast between the republican and democratic states. I also enlarged the fonts a bit for easier reading and the states of Alaska and Hawaii are bigger too. In addition to this I changed the labels of the states to their official two letter abbreviations for the original map lacked continuity in how each state was labeled--some states had two letter abbreviations while others had their whole name. The final thing that I changed was the position of the legend and inset maps to create more balance within the entire frame.

Again, I did not feel the need to make many improvements on the original map for I found it to be quite good. I especially liked how the bar separating the heading from the map of the Continental United States also doubled as a graph for the number of electoral votes Obama received versus McCain.

Well, today I am thrilled that the Bush regime has finally come to an end and now after this historic election, Barack Obama is our 44th President. CHANGE has finally arrived :)

Cartography Lab 1 - Census 2000





For this project I joined county-level race data from the 2000 Census and used it to create maps showing the population density of various races across the continental United States. I made three individual maps displaying Asian, White and Black race categories. I used the Lambert conic projection for all of my maps. I also chose to classify the race data by using natural breaks to model the data. I feel that using natural breaks instead of a preselected range of percentages yields a more accurate representation of the data that I am displaying.
When looking at the map of black race data it shows that in the year 2000 a higher percentage of blacks lived in counties found in the Southeastern states such as Louisiana, Mississippi, Alabama, Georgia, South Carolina, North Carolina and Virginia. Also near Chicago, Illinois there is a relatively large black population. Conversely the map of whites shows low population densities in these areas with high black populations. The maps look to be almost opposites of eachother. The map of Asian race census data shows that the highest population densities of Asians are found on the West Coast, especially around the San Francisco Bay Area. A guess to why this is could be that since the West Coast of the United States is closer to Asia, it would make sense that when Asians immigrated to the US that they would choose to live in the place that required the least amount of travel.

Geography Awareness


I stumbled across this great ad yesterday in a magazine for National Geographic's My Wonderful World campaign, which promotes global knowledge for children and the expansion of geographic learning in schools. Too many people these days forget that there is much more beyond America and are either too afraid to explore beyond our borders or too egocentric to care.
