The monthly variation throughout the year shows a sharp increase, especially in the months of April, May, and June, with peaks of 225, 275, and 249 complaints, respectively. Furthermore, a comparison between the first and second quarters of 2025 reveals an increase of over 100% in complaints (103.5%), rising from 368 to 749 occurrences.

The main reasons for complaints reflect the difficulties faced by citizens: inadequate or inefficient service (31.07%), technical and operational failures (26.23%), delays in processes and documentation (17.46%), scheduling and contact difficulties (15.94%), and problems with payments and transactions (6.62%). Other reasons reported on the Complaints Portal include staff misconduct and security issues.

AIMA's page on the Complaints Portal reveals the agency's poor performance in responding to the problems reported to it. Currently, it has a satisfaction rating of 18.1 out of 100, a response rate of 13.1%, and a resolution rate of 13.8%.

Pedro Lourenço, founder of Portal da Queixa, comments: "The increase of over 100% in complaints in the second quarter of 2025 reveals a serious, chronic, and structural problem. A public service cannot fail so systematically and devalue the suffering of those who depend on it. When the president of AIMA downplays complaints, he ignores the human impact of these failures. The State has an obligation to be exemplary, and silence in the face of delays and inefficient service is a sign of a lack of commitment to people."

Demographic analysis shows that most complaints come from Lisbon (34.65%), followed by Porto (17.91%) and Setúbal (10.47%). Regarding age group, the majority of those complaining are between 25 and 34 years old (42.70%), and there is a slight predominance of women (43.69%) compared to men (56.31%).
