THE FIRST O’REILLY SOFTWARE DEVELOPMENT SALARY SURVEY was conducted through an online survey hosted on Google Forms. More than 5,000 respondents submitted responses between January and May 2016, from 51 countries and all 50 US states, from companies both large and small, and from a wide variety of industries. Respondents were mostly software developers, but other professionals who program also participated in the survey.
Of the responses to the survey, 1,353 came from 27 countries in Europe, and those form the basis of the data in this report. The report on the worldwide findings, with some US-specific statistics, can be downloaded from O’Reilly’s web site.
When asking respondents about salaries, we recorded responses in US dollars, and therefore will use dollars throughout this report. The median salary of the entire EU sample was $56,000, with the middle half of all respondents earning between $35k and $80k. The latter statistic is called the interquartile range (IQR)—the middle 50%—and is used to describe the salaries of particular subsets of the sample in this report and its graphs. Imagine the IQR as a bell curve or normal distribution with the left-most 25% and right-most 25% cut off. The IQR is useful for showing the middle of the salary range without the distortion of outliers in the lowest and highest quartiles.
In each section we mention the relevant, significant coefficients, and at the end of the report we repeat those coefficients when we show the full ...
