In addition to that, in terms of not just planning for future transit and those types of issues--family time and quality of life--some of the issues around housing and the number of rooms versus number of people are used a lot, from an overcrowding perspective, for disease prevention planning, things like tuberculosis, influenza. Many of the respiratory conditions are far more easily spread in overcrowded situations.
It allows us to fine-tune a different type of approach for disease prevention planning based on where overcrowding is in our communities as well.
