Between May and August 2019, a total of 423 Myanmar nationals were interviewed in Yangon, Mandalay, Keng Tung, Tachileik and Golden Rock,
all of which have been previously documented as hosting wildlife markets. Respondents were selected at market locations through a systematic
intercept sampling approach (meaning every other individual encountered was interviewed) and quotas were set for gender and age. When
the sample was too small (e.g. elephant product buyers), booster samples were used to increase sample size and thus increase the power of
statistical significance tests.
