2. Dravidian Family: Spoken by approximately 19% to 20% of the population (includes Tamil, Telugu, Kannada, Malayalam, etc.).
3. Austroasiatic (Austric) Family: Spoken by about 1.1% of the population (includes languages like Santhali, Khasi, and Mundari).
4. Sino-Tibetan Family: Spoken by about 0.6% of the population (includes languages spoken predominantly in the Himalayan and Northeastern regions, such as Manipuri and Bodo).

Step 2: Identify the Second-Largest Group
Comparing the numerical proportions of speakers shows that the Indo-Aryan family ranks first, while the Dravidian language family ranks second largest in terms of total speakers in India.

Step 3: Conclusion
