In recent years, various plans have been implemented by the central government with the aim of promoting more coordinated policies to address depopulation. The severity of this challenge in Spain, which has continued to intensify, underscores the need for more decisive action. The information presented in this research is derived from a survey conducted in two rounds with 35 experts in the field, following the Delphi methodology. The general objective was to assess the opinions of an expert panel on relevant aspects concerning policies to combat depopulation in Spain. Firstly, confirming the significance of the depopulation challenge; secondly, evaluating whether the actions taken so far have been insufficient and poorly coordinated, necessitating a reconsideration; and finally, establishing a prioritization of actions that should be implemented without further delay, encompassing various areas (financing, taxation, coordination, etc.), are among the many measures advocated by the Spanish Federation of Municipalities and Provinces (FEMP) and proposed in the recent diagnoses by highly authoritative institutions such as the Bank of Spain or the Economic and Social Council of Spain (CES).
