Statistical analysis
The estimates were performed using the Respondent Driven Sampling Analysis Tool (RDSAT) version 5.6.0 [15]. To explore the information on mobility and working patterns, descriptive statistics and comparisons were done by two types of migrant workers, M1 and M2, among migrants from Cambodia and Myanmar. The social network size was defined as all migrants living in the same community that the participant knew by first name or vice versa, and with whom they had met in the past 30 days. RDSAT was used to calculate weighting of the samples to control for differences in network size and homophily of the population-based estimates for M1 and M2 populations. An analysis of homophily was done to determine the preference of members of a group for connections within one’s own group, in this case, M1 and M2. Homophily varies between -1 (completely
heterophilous, or having network connections
exclusively outside own’s group) and +1 (completely
homophilous, or having connections exclusively within
one’s group).
