2743200-114300Name: Section Color:Name: Section Color:Population DensityYour task: Use the following formula and the internet to complete the population density questions. The human population of different areas of the world can be studied by examining population density. Population density most often describes the number of people per square mile or number of people per square kilometer. You can calculate population density using a formula.Population Density = ____Population_____Area in square miles (or square kilometers)Example: Oregon’s population in 2006 was about 3.7 million. The State of Oregon is approximately 96,000 square miles. The population density of Oregon in 2006 was:Population Density = ____Population_____ = 3,700,000 = 38 people per square mileArea in square miles 98,000Internet search tips:For the population of states and countries:Type into the Google search window: Population of (Name of state or country)To find the size of a state or country:Type into the Google search window: Size of (Name of state)1. Find the current population density for the state of Oregon. Show your work. 2. Find the population density for Washington County.3. Do you think the population density of Washington County will increase or decrease over the next ten years. Explain your answer.____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________4.
