This pack contains a workflow, a file and documentation (tutorial to run the workflow).The Keyfit delta Workflow provides an environment to calculate the Keyfit delta value. Keyfitz’s delta is a measure of the distance between any two probability vectors (Keyfitz 1968). In this case is a measure of the distance between n (Observed Stage Distribution) and w (Stable Stage Distribution). The maximum value is 1 and the minimum value is 0 (when the vectors are identical).

Workflow A Comparison of China and US populations (2)

Thumb
This workflow is a comparison of China's population with the United States. It also compared the population of males and females from ages 0 - 4 to illustrate any gender gaps that may be occurring in the birth rates. The graphs are produced through the google chart API service. The data is from world population spreadsheets obtained from Gapminder.org.
