With the program nearing the end of the summer, it’s time for another round of updates!

2019 has been an epic year for Google Summer of Code as we celebrated 15 years of connecting university students from around the globe with 201 open source organizations big and small.

Mentors are the heart and soul of the Google Summer of Code (GSoC) program and have been for the last 14 years. Without their hard work and dedication, there would be no Google Summer of Code. These volunteers spend 4+ months guiding their students to create the best quality project possible while welcoming them into their communities – answering questions and providing help at all hours of the day, including weekends and holidays.

Thank you mentors and organization administrators! 

Each year we pore over heaps of data to extract some interesting statistics about the GSoC mentors. Here’s a quick synopsis of our 2018 crew:

• Registered mentors: 2,819
• Mentors with assigned student projects: 1,996
• Mentors who have participated in GSoC for 10 or more years: 46
• Mentors who have been a part of GSoC for 5 years or more: 272
• Mentors that are former GSoC students: 627
• Mentors that have also been involved in the Google Code-in program: 474
• Percentage of new mentors: 36.5%

GSoC 2018 mentors are from all parts of the world, hailing from 75 countries!


Another fun fact about our 2018 mentors: they range in age from 15-80 years old!

• Average mentor age: 34
• Median mentor age: 33
• Mentors under 18 years old: 26*

GSoC mentors help introduce the next generation to the world of open source software development – for that we are very grateful. To show our appreciation, we invite two mentors from each of the 206 participating organizations to attend our annual mentor summit at the Google campus in Sunnyvale, California. It’s three days of community building, lively debate, learning best practices from one another, working to strengthen open source communities, good food, and lots and lots of chocolate.

Thank you to all of our mentors, organization administrators, and all of the “unofficial” mentors that help in the various open source organization’s communities. Google Summer of Code is a community effort and we appreciate each and every one of you.

Cheers to yet another great year!

Mentors are the bread and butter of our program - without their hard work and dedication, there would be no Google Summer of Code (GSoC). These volunteers spend 12 weeks (plus a month of community bonding) tirelessly guiding their students to create the best quality project possible and welcoming them into their communities - answering questions and providing help at all hours.

Each year we pore over oodles of data to extract the most interesting and relevant statistics about the GSoC mentors. Here’s a quick snapshot of our 2017 group:

• Total mentors: 3,439
• Mentors assigned to an active project: 1,647
• Mentors who have participated in GSoC over 10 years: 22
• Percentage of new mentors: 49%

GSoC 2017 mentors are a worldly group, hailing from 69 countries on 6 continents - we’re still waiting on a mentor from Antarctica… Anyone?

Interested in the data? Check out the full list of countries.

Some interesting factoids about our mentors:

• Average age: 39
• Youngest: 15*
• Oldest: 68
• Most common first name: Michael (there are 40!)

GSoC mentors help to introduce the next generation to the world of open source software development — for that we are very grateful. To show our appreciation, we invite two mentors from each of the 201 participating organizations to attend the annual mentor summit at the Google campus in Sunnyvale, California. It’s three days of food, community building, lively debate and lots of fun.

Thank you to everyone involved in Google Summer of Code. Cheers to yet another great year!

Our final statistics post of the year is dedicated to to the incredible Google Summer of Code (GSoC) 2016 mentors. There were a total of 2,524 mentors, but today we'll look at the 1,500+ mentors who were assigned to an active project. Mentors are the lifeblood of our program. Without their hard work and dedication to the success of our students, there would be no GSoC. A merry band of volunteers, mentors work with students for more than 12 weeks — remotely, across multiple time zones, giving their time, expertise and guidance in addition to a regular full-time job for an average of 7.45 hours a week. Today we’ll take a closer look at our 2016 team.

GSoC 2016 mentors reside all over the world and represent 66 countries.

Google Summer of Code (GSoC) 2016 is officially at its halfway point. Mentors and students have just completed their midterm evaluations and it’s time for our second stats post. This time we take a closer look at our participating students.

First, we’d like to highlight the universities with the most student participants. Congratulations are due to the International Institute of Information Technology - Hyderabad for claiming the top spot for the third consecutive year!

Country	School	2016 Accepted Students	2015 Accepted Students	12 Year Total
India	International Institute of Information Technology - Hyderabad	50	62	252
Sri Lanka	University of Moratuwa	29	44	320
Romania	University POLITEHNICA of Bucharest	24	14	155
India	Birla Institute of Technology and Science Pilani, Goa Campus	22	15	110
India	Birla Institute of Technology and Science, Pilani Campus	22	18	116
India	Indian Institute of Technology, Bombay	18	13	75
India	Indian Institute of Technology, Kharagpur	15	8	92
India	Indian Institute of Technology, Roorkee	15	8	57
India	Indraprastha Institute of Information Technology Delhi	15	7	27
India	Amrita School of Engineering, Amrita University, Amritapuri Campus	13	5	33
India	Indian Institute of Technology, Guwahati	13	5	38
Cameroon	University of Buea	12	10	26
India	Delhi Technological University	12	9	60
India	Indian Institute of Technology BHU Varanasi	12	12	37
Germany	TU Munich	11	7	45

Next, we are proud to announce that 2016 marks the largest number of female GSoC participants to date — 12% of accepted students are female, up 2.2% from 2015. This is good progress, but we are certain we can do better in the future to diversify our program. The Google Open Source team will continue our outreach to many organizations, for example, Grace Hopper and Black Girls Code, to increase this number even more 2017. If you have any suggestions of organizations we should work with, please let us know in the comments.

Finally, each year we like to look at the majors of students. As expected, the most common area of study for our participants is Computer Science (approximately 78%), but this year we have a wide variety of studies including Linguistics, Law, Music Technology and Psychology.  The majority of our students this year are undergraduates (67%), followed by Masters (23%) and then PhD students (9%).



Although reviewing GSoC statistics each year is great fun, we want to stress that being “first place” is not the point of the program. Our goal is to get more and more students involved in creating free and open source software. We hope Google Summer of Code encourages contributions to projects that have the potential to make a difference worldwide. Congratulations to the students from all over the globe and keep up the good work!

We share statistics from Google Summer of Code (GSoC) every year — now that 2016 is chugging along we’ve got some exciting numbers to share! 1,206 students from all over the globe are currently in the community bonding period, a time where participants learn more about the organization they will be contributing to before coding officially begins on May 23. This includes becoming familiar with the community practices and processes, setting up a development environment, or contributing small (or large) patches and bug fixes.

We’ll start our statistics reporting this year with the total number of students participating from each country:

Country	Accepted Students	Country	Accepted Students	Country	Accepted Students
Albania	1	Greece	10	Romania	31
Algeria	1	Guatemala	1	Russian Federation	52
