Okay kiddo, so demographics mean information about the people who live in a place like Austria. Austria is a country in Europe, and it has about 9 million people living there.
Let's look at the ages of those people. There are more older people in Austria and fewer younger people. About 19% of the population is over 65 years old, which means they are retired from work, and they might need more help from others. There are fewer children, and only about 15% of the population is under 15 years old.
Austria has different languages spoken in different parts of the country, but most people speak German. The majority of the people are Austrian or German, but there are also other people from different countries living in Austria.
Now, let's talk about religion. This means what people believe in, like God or gods or nothing at all. The most common religion in Austria is Christianity, but there are people who follow other religions like Islam or Judaism or they don't have any religion at all.
Lastly, let's talk about education. Austria has a high literacy rate, which means that most people can read and write. Education is very important in Austria, and people usually go to school until they are 18 years old. People can also go to university and study different things like medicine, law, or engineering.
So in summary, Austria has an aging population with fewer children, German as the most commonly spoken language, Christianity as the most commonly followed religion, and a high emphasis on education.
