Hi Barry:

My colleagues and I modeled the probability the probability of Facebook friendships between friends of a sample of young, Black men who have sex with men, who were recruited for an HIV prevention study in Chicago. Our data and analyses are published in https://urldefense.proofpoint.com/v2/url?u=https-3A__www.jmir.org_2018_9_e11652_&d=DwIGaQ&c=sJ6xIWYx-zLMB3EPkvcnVg&r=yQQsvTNAnbvDXGM4nDrXAje4pr0qHX2qIOcCQtJ5k3w&m=DDKap1_yrc6Eux_P6q0fewZnUDWmQ4MkElgQvYhzbyQ&s=HqF8UOuLfUdR6Q3Awa--KXWAynaM776foRhH5k7bKOY&e= . 

Many thanks,
Aditya

    Hi Barry -
    
    See the attached paper, specifically Figure 6 and the text section 
    "Racial selective mixing and the prevalence of sociodemographic categories"
    
    The context is a comparative analysis of many US middle and high schools.
    
    Cheers,
    
    Steve
