Core Taxonomy
Our Core Taxonomy introduces important changes to ESCO to better reflect the livelihoods and economic realities in low- and middle-income countries, but avoids country-specific adaptations.
Our Inclusive Livelihoods Taxonomy introduces important changes to ESCO to better reflect the livelihoods and economic realities in low- and middle-income countries. This page presents our standardized Core version, which is not country-specific. We use our Taxonomy Management Platform to manage and maintain various adapted and country-specific versions.
Version 1.0.0
Version 1.0.0 of the Core Taxonomy expands conventional job and skill classifications by changing ESCO v.1.1.1 in the following ways:
Including New Occupations: Such as "Micro-entrepreneur," explicitly recognizing self-employed individuals and small-scale entrepreneurial activities.
Capturing Unseen Economic Activities: Integrating overlooked roles and activities such as caregiving, housework, volunteer work, and informal employment, guided by the International Classification of Activities for Time-Use Statistics (ICATUS) 2016.
Enhancing Accessibility: Adding simplified alternative labels and clearer terminology, making the taxonomy more approachable and easy to use.
Ensuring Data Quality: Regularly refining taxonomy entries by fixing missing labels, removing duplicate records, and standardizing formatting and textual clarity.
