        Income inequality, a pervasive challenge that hinders economic progress and social well-being, demands innovative solutions. This app tackles this issue head-on, harnessing the power of machine learning to predict individual income levels.

        **Key Challenges of Income Inequality:** ⚠

        1. **Limited Economic Mobility:** 📉

            Individuals from lower-income households often face barriers to education and professional growth, perpetuating income disparities.

        2. **Healthcare Disparities:** 🩺

            Income inequality often translates into unequal access to quality healthcare, leading to adverse health outcomes for lower-income individuals.

        3. **Education Gaps:** 📚

            Children from low-income households may have limited access to quality education, hindering their future opportunities.

        4. **Social Unrest:** 💢

            Extreme income inequality can fuel social unrest as individuals feel disenfranchised and discouraged.

        5. **Economic Impact:** 📉

            Income inequality impedes economic growth by reducing aggregate demand and creating economic instability.

        6. **Policymaking Challenges:** 🧩

            Policymakers require accurate data and insights to formulate effective strategies for reducing income inequality.
