Challenges to traditional survey data collection such as increased costs and decreasing non-response are leading survey researchers to explore new forms of data. Recently, two types of data have received increased focus as a possible replacements or enhancements of surveys: digital trace data and data donation. Digital trace data refers to data produced while individuals interact with digital platforms, such as apps and websites. Data donation, on the other hand, refers to the acquisition of data from online platforms, such as Facebook or Google, directly from users. In a recent study we use an experimental design in a non-probability panel in Germany to explore non-response bias in data donated from Facebook as well measurement error in digital trace data from PCs and mobile phones.
