Two of the questions we’re often asked here at StreetLight Data are: “What percentage of the population is creating the location records in your sample?" and "Does the location data in your sample fairly represent all income groups, or is it biased?” In this blog post, we’re pulling back the curtain on our internal evaluation process with a deep-dive analysis of our newest data source: Location-Based Services data. We started using this data source chiefly because of its large sample size and representativeness, so in this blog post, I will show you our process for determining these characteristics. (Click here to read more about Location-Based Services data in general.)
Fehr & Peers has published an excellent and detailed project report here. They did all the work involved in the validation. We have merely summarized the results most relevant to StreetLight validation questions below.

"A Note from StreetLight: We are starting a series of blogs on the theme of "data validation." Since StreetLight measures behaviors that are generally hard to measure, it presents a challenge for validation (what's the baseline?). We are collecting cases where good baseline data is available and publishing our findings. If you have suggestions for future editions of the validation blog please get in touch! We're very glad to have a guest blogger, Dave Chipman from Men's Wearhouse, for our initial post. ~Laura Schewel, CEO of StreetLight
