Assessing global data set on PWID and HIV
1) By methodology of the estimates;
2) By year of the estimates

Pop Size of People Who Inject Drugs Global classification of country estimatesGRADE METHODA Indirect prevalence estimation methods
(capture-recapture, multiplier methods, etc)B General population surveyC Treatment and other national registersD1 Experts’ judgment with known method of estimation (e.g. obtained
through a rapid assessment);Delphi method or other consensus estimate;Official government estimate with no methodology reported
D2* Estimate with methodology unknown
* Data graded D2 excluded from the UN dataset

HIV among People Who Inject Drugs Global classification of country estimatesGRADE METHODA Multi-site seroprevalence study with at least two sample types
(e.g. treatment or outreach sample); Seroprevalence study from a single sample type
B Registration or notification of cases of HIV infection (e.g. from treatment services)
C Prevalence study using self-reported HIV D1 Official government estimate with no methodology reported;
Modelling studies (e.g. mode of transmission models)
D2* Estimate with methodology unknown
* Data graded D2 excluded from the joint UN dataset

Still, many countries1) Currently have PWID
estimates, which are critically outdated and/or
2) Currently have PWID estimates which are methodologically very weak
or3) Do not have PWID and/or
PWID/HIV estimates at all
