Mapping The Titanic’s Passengers

By Matt Stiles | | Topics: Uncategorized

Mapping software giant Esri has recently published “story maps,” self contained interactives in which maps anchor the narrative. The latest example uses symbols on a world map to show the destination cities of Titanic passengers. Larger symbols represent more passengers traveling to a specific destination. It also has a pie chart showing how many survived the disaster:

Using the top navigation bar you can toggle the maps to see how passengers in the various ticket classes fared. More than half of the first-class passengers survived, for example, while only about a quarter of the third-class passengers (think Leonardo DiCaprio‘s character) survived:

U.S. Population Growth

A cross post from work:

The U.S. Census Bureau released its final batch of state-by-state redistricting data this week, making it possible to visualize population growth by race and Hispanic origin across the country.

Texas received its data several weeks ago, and we displayed these trends by counties and legislative districts in two interactive maps.

Like Texas, the nation saw divergent growth patterns, with some counties booming and others losing population. The state also kept pace nationally in the rate of Hispanic population growth. The Texas Hispanic population increased 42 percent in the last decade. The country saw a 43 percent increase.

This map shows population growth among all races in each of the more than 3,141 counties (and county equivalents). Red shades represent counties that lost population, and darker green shades represent those with higher rates of growth. 

This map has a similar view, but shows the rate of Hispanic growth:

I’ve also uploaded high-res PDF files (all population, Hispanic) and the raw data behind the maps.

D.C. Census Drops (Finally)

By Matt Stiles | | Topics: Uncategorized

The U.S. Census Bureau today released redistricting data for the District of Columbia, a city that at first glance remains quite segregated — at least in terms of where people live. These quick maps visualize the percentage of black residents by census tract in 2000 and in 2010. 

First, 2000:

Now for 2010. Notice that some neighborhoods are becoming more diverse, but not that many. Fewer than I expected, actually, given all I’ve heard about gentrification in D.C., where I moved last week. 

(More to come).
