Do you know the population of your state? What does population really mean? In this lesson we will talk about population! We will also look at what kind of data population requires!

Which state in the United States do you think has the most individuals? Well, in the year 2015, there were over 39 million people living in the state of California according to the United States Census Bureau, making it the state with the most people in the country! Wow!

Now, which state do you think has the least amount of individuals? In the year 2015, there were just over 586,000 individuals living in the state of Wyoming according to the United States Census Bureau. What we just compared was the population between the states of California and Wyoming!

Population tells us how many individuals live in a certain area. So, when the United States Census Bureau wanted to figure out how many individuals live in California or Wyoming, they recorded the population by counting all individuals residing in those two states. Now, of course they did not do a head count by counting each person all the way from 1 to 586,000 or from 1 to 39 million! That would take forever! The United States Census Bureau records the population by passing out surveys or questionnaires for families to fill out.

When the United States Census Bureau records the population, they need to collect data from all families. Think of data as simply information that is gathered and analyzed. There are two types of data: quantitative and qualitative.

### Quantitative Data

Let's dive into quantitative data. Quantitative data is information that can be given with numbers. You can remember what quantitative means by thinking of the word quantity, or how much of something. When the United States Census Bureau figures out the population of each state, they need to gather quantitative data since they are figuring out the number of individuals living in each state.
