Duties and Responsibilities

There is an urgent need to strengthen the capacity of national statistical systems to leverage the use of innovative and administrative data for statistical purposes, to fill gaps in the data that is available to policy and decision makers to monitor progress and implement the 2030 Agenda and to address emerging challenges. Many countries are still struggling with the lack of modern IT infrastructure and technical skills, along with adequate institutional arrangements, for the efficient integration and processing of data and metadata from administrative and other innovative sources, to produce official statistics. The UN Statistics Division of the Department of Economic and Social Affairs (DESA) is engaged in capacity development efforts aimed to address some of these challenges, including through the “Data for Now” initiative, including through the “Data for SIDS” DATAS project. These initiatives support various countries in their work to improve and increase the use of innovative and administrative data sources for statistical purposes, with a different area of focus in each country. The learnings and experiences from participating countries will be further shared with other countries to create synergies and multiplicative effects, including through cross-cutting guidance materials that will supplement existing thematically focused materials and tools. Objective of the consultancy The objective of this consultancy is to support national statistical offices (NSOs) in modernizing their IT architecture, in particular through the design, configuration, and deployment of a modular, open-source data lake technology stack (e.g. Apache NiFi, MinIO, JupyterHub, Trino, open-metadata, Kubernetes) aligned with international standards. The consultant will support the development of in-house data engineering skills in NSOs and provide practical guidance and other reference materials to enable the sustainable modernization of their data and IT architecture. Work Assignment The consultant will: • Work closely with IT and statistical focal points of NSOs to gather information on existing IT systems, assess hardware, software, and skillset requirements, draft technical requirements, and provide technical advice to modernize them, including on data ingestion, storage, processing/analytics, dissemination, and security and access management. • Develop a report with a summary of requirements and technical recommendations for the modernization of IT architecture in at least 2 Data for Now project and DATAS countries. • Delivery of technical assistance and advice (through remote sessions and potentially country missions) to facilitate the implementation of the technical recommendations for the modernization of IT architecture, including hands-on support for deployment and configuration of the minimum data lake technology stack. • Provide trainings and knowledge sharing of the platforms and technology stack deployment and use on data lake architecture to internal and external stakeholders. • Support development of country case studies around the modernization of IT architecture that facilitates the integration and use of innovative and administrative data sources into the production of official statistics. • Support development of general guidance on IT architecture and infrastructure related to the use of non-traditional data sources, initially for administrative data, but potentially also expanded to other innovative sources. • Where and if applicable, ensure adherence to UN policies and data governance frameworks
