Track the Trends—Predict the FUTURE?


CALIFORNIA:
Still the Golden State?


By Kristina & Marc
Overview
Who are we?
A committee of demographers in the State Department of Finance
What do we do?
Examine population trends in the state
Predict overpopulation effects
Analyze the implications on state resources and quality of life
Why is it important?
To be able to prepare and plan for possible overpopulation implications and effects before they occur
Our Presentation
Analyzing California’s Population Trend and future predictions
Implications and effects
Recommendations
California Population
Using the US Census Web site, we found the following historical population data (in millions):
Creating the Formula From the Data
x = number of years since 1890
y = population of California

Formula y = 1.323 • 1.033x
Correlation r = .994
The formula means that population started at 1.323 million people and increased 3.3% per year on average since 1890.
Graphing the Results
The exponential formula nearly matches the actual historical data.
Future Predictions
Using the formula y = 1.323 • 1.033x , predictions can be made about California’s future population.
For example, 2050 is 160 years since 1890 1.323 X 1.033160 = 238.6 million.
Implications
California is going to be overpopulated and overcrowded.
In 1990, the population was 30 million.
In 2010, the population will be 65 million, more than double 1990’s population.
In 2050, the population will be nearly equal the entire population of the current United States.
Possible Effects of Overpopulation
Traffic gridlock
Energy shortages
Water shortages
Environmental deterioration
Increased crime
Our Recommendations
Further study and data trend analysis is needed on the possible effects of overpopulation on the state’s resources and quality of life.

We recommend that data analysis be completed to obtain information about the relationships between overpopulation and effects such as traffic gridlock, energy and water shortages, environmental deterioration, and increased crime. This will allow us to use data in preparing for and solving our state’s problem.
