For nearly half of the gender-specific indicators, the methodology is developed but country-level data are limited. As of December 2017, the framework contains 93 indicators classified as Tier I, 66 as Tier II and 68 as Tier III. In addition, five other indicators are classified as multi-tier, with different components of the indicator classified into different tiers. Additionally, the lAEG-SDGs is currently liaising with custodian agencies to discuss available data sources and methodology to improve the availability and quality of country-level data related to Tier II indicators.
