Structure Purpose and Methodology Characteristics of F/LOSS Developers F/LOSS versus Closed Source Software Motivations of F/LOSS Developers Motivations of F/LOSS and Close Source Software Developers Motivations of High and Low Activity F/LOSS Developers

Purpose of the Developer Survey Personal Features of F/LOSS Developers (socio-economic background, demographics) Work and Project Organisation Relation between Open Source and Free Software Relation to Closed Source Software Rewards (monetary and non-monetary) Motivations, Expectations, Orientations

Methodology of Developer Survey Global (random sample, web-based) ~2800 responses, verified against software source code authorship Detailed questionnaire: 42 questions on demography, orientations, motivation, earning/ employment

Structure Purpose and Methodology Characteristics of F/LOSS Developers F/LOSS versus Closed Source Software Motivations of F/LOSS Developers Motivations of F/LOSS and Close Source Software Developers Motivations of High and Low Activity F/LOSS Developers

Image of Software Developers in the Public  (According to Douglas Coupland’s “Microserfs”) “Nerd” : Male Home- and Computer-sticking Only Interested in Software and ICT Earning relatively high incomes Only Software Developers / Engineers as Friends (most of them known by ) hours “working night” (enabled by Prozac) Single Free Software/Open Source: Students

Evidence from F/LOSS Survey I Gender: – 98.9% male, 1.1% female Age: –Ranging from 14 to 73 –2/3 between 16 and 36 –average age: 27.1 years Starting Age –Average: 22.9 years –7% below 16 years, 2/3 between 16 and 25 years, and roughly 1/4 older than 25

Evidence from F/LOSS Survey II “Civil Status”: –Singles: 41% –Partner, not living together: 19% –Partner, living together: 19% –Married: 21% –Children: 17%

Evidence from F/LOSS Survey III Educational Background: –Elementary School: 2% –Apprenticeship: 3% –A-Level / High School: 25% –University degree (61%) –PhD: 9%

Evidence from F/LOSS Survey IV Hours of Work per Week Spent for F/LOSS:

Evidence from F/LOSS Survey V Professional Background:

Evidence from F/LOSS Survey VI Employment Status: –Employees: 65% –Self-employed: 14% –Students, no paid work 17% –Not working at the moment: 2% –Unemployed: 2%

Evidence from F/LOSS Survey VII Monthly Gross Income:

Evidence from F/LOSS Survey VIII Conclusions: –Young and male community –High educational level –Strong professional background in IT sector –Students are second largest group –49% do not spend more than 5 hours/week –Most are married or coupled –Relatively high share of self-employed, very few unemployed –High incomes are rather untypical  “Nerd”-image is definitely wrong
