Social Hangouts for German Teenagers
After an extensive search in English and German, there are no publicly-available studies, surveys, datasets, or articles that breakdown the proportion of time that German teenagers spend on different leisure activities with friends or the relative popularity of each one. To indicate what is and isn't available on this topic, I have provided a deeper than usual overview of my research methodology for your reference along with some useful paywalled resources on Statista on how German teenagers and children spend their time. I have estimated how much overall free time German teenagers have to spend with friends on entertainment activities in case that is useful to you. On average, German teenage girls have at most 25.2 hours per week to spend with friends and German teenage boys have at most 16.1 hours.
I began by reviewing the first response to your question and confirmed that following group leisure activities of teenagers in Germany are accurate: social hangouts at clubs, concerts, discos, bars, and friends' homes as well as attending soccer matches. I searched for additional activities such as going to the cinema or additional sports, but did not find anything significant enough to include in the list.
Since you are most interested in the proportion of time German teenagers spend on these activities as well as their relative popularity, I concentrated the bulk of my research on finding statistics for each activity type as well as on German teen leisure time as a whole. I methodically searched for industry and government reports, academic studies, datasets, articles, and resources for German teenagers and parents on how German teenagers spend their free time with friends.
When English did not yield results, I used a translator to search German sources. I also approached the topic indirectly, by searching for global and European reports that might break out Germany. For example, I was hopeful that this European Youth Trend Report would have usable data, but most of the report is on Europe as a whole with limit insight into Germany. Finally, I went back several years to identify past reports that may be no longer paywalled, but found a similar lack of information.
After researching the topic extensively, I confirmed that there is a dearth of publicly-available data on the average amount of time German teenagers spend on group leisure activities. It may be that this information is available behind paywalls or scholars and researchers may not yet have studied this topic in detail. It is also possible that German teen's have diverse interests, making it difficult to establish average activity times or relative popularity of entertainment places and activities.
Statista has a couple recent datasets on German children and German teens' leisure activities that may have useful data on this topic. You may be interested in the following:
"Popular leisure activities among children in Germany 2016, by gender"
This dataset indicates leisure activities popular among German children. One interesting available statistic from this set is that "56 percent of German girls stated that meeting friends was among their favorite leisure activities, compared with 54 percent of German boys." A 2015 version of this report is available in German and has more information on German children's leisure activities such as that around 27% of German children like to go shopping, 14.3-15.7% like to go out for dinner, 7.5%-8.6% like to go jogging, and 7.4-7.9% like to play board games. However, data on age group and whether these activities are with friends, family, or alone is not publicly available. I also identified a brief article stating that more Germans are interested in going to concerts than football matches, but it did not have specific data for teenagers or more information on why this is the case.
"Regular leisure activities of children in Germany 2016"
This dataset indicates how children spend their time and may have detail into the group activities of German teenagers. Interestingly, it points out that "70 percent of German children" do homework or study every day which eats into the total time they have available to spend with friends.
USEFUL FINDINGS on time spent HANGING OUT WITH FRIENDS
During my research, I gathered statistics on how German teens spend their time in general to triangulate an estimate of how and where they spend their group leisure time. Unfortunately, as no data is publicly available on the specific time they spend on group leisure activities, I was only able estimate the average amount of time German teens likely have available to spend on leisure activities with their friends. Though this does not directly answer your question, it does provide an overall scope of how much time in total German teenagers have to spend at the places you are interested in.
In reality German teenagers likely have varied schedules, but the values below are estimates to provide a general sense of the amount of time they have available for group leisure activities. In a 168-hour week, the average German teenagers spend their time in the following ways.
63 hours sleeping
The average German gets around 8 hours of sleep per night between the hours of 11pm and 7am. Meanwhile, the recommended amount of sleep for a teenager is 10 hours per night. To make sure I'm neither understating nor overstating the amount of sleep German teens get, I averaged the two values for an estimate of 9 hours per night or 63 hours per week. This value also seems reasonable given the common 8am start time of German schools, meaning that most teens would be in bed by 10pm, slightly earlier than their parents.
40 hours at school
Although many schools in Germany continue to be part-time with hours from 8am-12pm, many schools are changing to an all-day model with students leaving at 4pm. Even schools with a part-time schedule, usually have mandatory or voluntary sports and extracurricular activities in the afternoon that keep students at school until 4pm.
5 hours getting ready and going to school
As listed above, the average German wakes up around 7am. This gives the average German teen an hour to get ready and get to school by 8am.
4.7 hours on homework
The average German student spends 4.7 hours a week on homework. I found no data indicating that German teenagers vary from this overall statistic for German students.
This means that the average German teenager has 55.3 hours per week to spend on leisure activities. However, not all of that time is spent in places hanging out in person with friends.
14 hours spent online
89% of German teens use the internet daily and 8% use it weekly, bringing the total value to 97% of teens use the internet per week. On average, German teens age 16-18 spend at least 2 hours online per day. Some of this time is spent chatting with friends over Skype, email, messaging, and social networks, but again not in person. The amount of time German teenagers spend on the phone is not publicly available; however, it also likely overlaps with time spent in school and doing other activities.
11.2 hours watching TV
Germans aged 14-29 spend an average 96 minutes or 1.6 hours per day watching TV. Some of this time may involve teenagers watching TV together at each other's homes. Unfortunately no data is available on the people with whom teenagers are watching TV.
4.9 – 14 hours playing video games
German girls spend 42 minutes or 0.7 hours per day playing video games, while German boys spend 124 minutes per week day playing video games, likely with an increase on the weekend. There is no information on how much of this time is spent playing in person with friends. To avoid overstating the value of this time, I have simply used the per week time for girls and per week day time for boys. I also searched for other independent activities that would eat into leisure time with friends. Though no time data is available, 40% of German teenagers read books daily to several times a week.
Working in time spent on the internet, watching TV, and video games brings the estimated free time German teenagers have to spend with friends per week to 25.2 hours for girls and 16.1 hours for boys on average.
To further tighten the estimate, I searched for the average time German teenagers spend with their families. No specific data is available on family time; however, an article in Time suggests that most German parents "place a high value on independence and responsibility" and time outside. This may indicate that German parents have a hands-off approach to how their teenagers spend their leisure time. As there are no specific data points for family time, I have excluded it from the estimate.
Regarding time German teenagers spend working, at ages 13 — 14, teenagers can have a part-time job with parental permission. 15-18 year-olds may work up to four weeks on summer holidays at a maximum of 40 hours per week. Teenagers that are no longer in "compulsory education" can work up to 40 hours a week between 6am — 11pm depending on the job type. There are also exceptions for children in theater, music, and media such as actors and musicians. Despite significant information on these requirements, I could find no average amount of time teenagers spend working likely because it differs based on age and on a case by case basis. However, it does seem that during the bulk of the year when teenagers are in school, the majority of them cannot work. As such, I have excluded work from the estimate.
On average, German teenage girls have at most 25.2 hours per week to spend with friends and German teenage boys have at most 16.1 hours. That time does not include family time, time spent working, travel time to activities, time spent getting ready for activities, or other independent activities like reading, so is likely an over-estimation of the total time they have. I hoped to then find estimates for some activities identified in the previous request to triangulate the relative time German teenagers spend on each activity within their available time. Unfortunately, no data is available to estimate those values.
After an extensive search, there is no publicly-available data on the relative popularity of entertainment venues where German teenagers spend their time. I have provided a deep dive into my research methodology to indicate what is and isn't available on this topic. I also triangulated an estimate of the total amount of free time German teens have per week to spend with their friends. On average, German teenage girls have at most 25.2 hours per week to spend with friends and German teenage boys have at most 16.1 hours.
