2Overview
- Water Use Data
- Texas Water Development Board
- www.twdb.state.tx.us
- Health Data
- Texas Department of Health Services
- www.dshs.state.tx.us
- Low Birth Weight
- Death rates
- Overall
- Due to specific causes
- All Data for 2002, separated by county

10Lettermans Top 5 Causes of Death by County
11Where are these Counties?(So we know to stay
away from them)
12Conclusions
- Typical grad student conclusion none
- No obvious statistical correlation between
municipal water use and overall health - Possible Sources of Error
- Misinterpretation of Municipal Water Use
- Population Errors skew death rates higher (or
lower) - Statistical Misleading Spacing of Color
Classification
13Future Work(For Written Report)
- Larger Time Period
- More Statistical Research
- Leading causes of death in county vs. water
consumption - What the heck is going on in Maverick County?
- For starters, No. 5 and No. 6 Top Employers in
Eagle Pass (Maverick County Seat) are a Casino
and a Shotgun Manufacturer
