On April 20, Guro District announced the results of its 'Resident Income Structure Big Data Analysis,' which tracked three years of income mobility for all residents—the first such initiative among local governments nationwide.

By analyzing anonymized credit data (KCB) from 2023 to 2025, Guro District's Gini coefficient decreased for three consecutive years, from 0.2449 to 0.2395. The closer the Gini coefficient is to zero, the more equal the income distribution. This indicates that income inequality in Guro District is gradually improving.

Income mobility was also found to be active. The rate of upward income mobility was 29.5%, which is 1.6 times higher than the downward mobility rate of 18.3%. Among residents who exited the low-income group (the first and second quintiles), approximately 72% moved into the middle-income group. As a result, the proportion of middle-income residents expanded from 42.3% to 45.4%, marking a 3.1 percentage point increase.

By age group, the upward trend was most pronounced among young adults. Upward income mobility in the youth segment was about six times higher than downward mobility, showing a much stronger upward trend compared to other age groups.

This analysis was conducted at a granular level, using 100-meter grid units rather than just administrative districts. Through this method, the district was able to obtain foundational data to closely identify areas of income stagnation and clusters of households at risk. The analysis not only assessed the current state of income but also examined individual-level income mobility over time, allowing for a multi-dimensional view of changes and trends in local income distribution.

Based on these results, the district plans to develop customized policies tailored to local conditions and strengthen data-driven administration to advance the 'Guro-style Basic Society' initiative. A Guro District official stated, "We will continue to identify and implement policies that residents can truly experience through ongoing data-based analysis."
