The rise of Generation Alpha Generation Alpha is the most recent to have been named, and many group members will not be able to remember a time before smartphones and social media. However, the group already makes up around 42.75 percent of the U.S. population, and they are said to be the most racially and ethnically diverse of all the generation groups, with the oldest Generation Alpha members aging into adolescents this year. Boomers vs. Millennials The number of Baby Boomers, whose generation was defined by the boom in births following the Second World War, has fallen by around seven million since 2010.

Across all generations in Germany, it seemed that having good friends and close relationships was very important to people.

The Allensbach Market and Advertising Media Analysis (Allensbach Markt- und Werbeträgeranalyse or AWA in German) determines attitudes, consumer habits and media usage of the population in Germany on a broad statistical basis. Generational differences The largest generations in Germany are Generation Y (also known as Millennials) and Generation X. Each generation has different defining characteristics, for example, Gen Z grew up with technology and are often characterized as being especially worried about their future. Millennials were the first generation to experience the transition from an analogue into a digital world whilst they were growing up and are therefore sometimes referred to as digital natives. Another large difference between generations is political allegiance. Die Grünen (the German Green Party) was especially popular among Generation Z. Whilst with Generation Y and Generation X, the CDU and SPD had stronger support. Leisure activities Although there are some differences there are also many similarities between generations. When it comes to leisure activities, for example, shopping, eating out, and photography were enjoyed by all. As expected, however, there are also some differences. Computer games and going clubbing were mostly undertaken by Gen Z, whilst hiking was a more common pastime among Gen X. In general, some of the most popular hobbies in Germany included socializing, cooking/baking, as well as various types of outdoor activities. In contrast, the most common ways for people in the U.S. to spend their free time included cooking, reading, and spending time with pets.
