Introduction

The Household Economy Analysis (HEA) Database serves as a pivotal resource in the assessment and understanding of household economies across various regions. Its creation and ongoing management enable a structured approach to data storage and presentation of the livelihood strategies and other characteristics of households within diverse livelihood zones.

One of the important opportunities presented by the HEA Database is its ability to standardize the language and classification used across the range of baseline surveys and the resulting Baseline Storage Sheets (BSS) for each country. This standardization plays a crucial role in enhancing the comparability and coherence of data, which, in turn, is instrumental in:

  • Ensuring Consistency: By adopting international standards and a uniform set of terminologies for metadata, the database ensures that data collected from different regions or studies can be compared and analyzed in a consistent manner. This consistency is fundamental for aggregating data at a national or regional level, thereby providing a comprehensive overview of livelihood strategies.

  • Facilitating Cross-Regional Analysis: Standardization of language and classification across BSS allows for the direct comparison of data across different countries and regions. This comparative analysis is essential for identifying patterns, trends, and anomalies in household economies.

  • Improving Data Quality and Reliability: Standardized data storage and classification methodologies contribute to the overall quality and reliability of the data stored in the HEA Database. This reliability is critical for stakeholders, researchers, and policymakers who depend on accurate and comparable data to make informed decisions.

  • Enhancing Accessibility: A standardized language and classification system make the database more accessible to a broader audience, including international agencies, non-governmental organizations (NGOs), and researchers unfamiliar with local terminologies. This accessibility is pivotal for collaborative efforts and knowledge sharing on a global scale.

  • Enabling Data Integration: The use of global metadata standards, such as ISO 3166 for countries, ISO 4217 for currencies, and the Central Product Classification (CPC) v2.1 for products, allow current data for items such as market prices and crop year forecasts to be compared to the data for the reference year, easing the use of HEA data in outcome analysis.

Approach

To effectively manage metadata within the HEA Database, the following practices are implemented:

  • Data Entry and Validation: All metadata entries are subject to validation against the respective standards before inclusion in the database. This ensures accuracy and consistency of the data.

  • Data Ownership: Each metadata item has an Owner and designated Editors. The Owner is ultimately responsible for data quality for that metadata item. This approach ensures that someone has a full picture of the individual metadata items and can avoid duplicates, etc.

  • Regular Updates: Metadata standards, especially wealth characteristics, are periodically reviewed and updated to reflect changes in economic practices and data classification standards.

  • Training and Documentation: Personnel involved in metadata management are provided with training and detailed documentation on metadata standards.

  • Quality Assurance: Regular audits of the metadata are conducted to ensure adherence to standards and to identify and correct any inconsistencies.
