Don Bosco higher secondary education school was established in Pannur in 1958, with the help of then village President Shri. Bashyam Jacob Naidu, a great Salesian priest Rev. Fr. Ittyatchan S.D., and the village parish priest Rev. Fr. D. Joseph D.D. The first SSLC batch graduated in 1962.

In 1953 Pannur began trading groundnut, paddy, and ragi. The first rice mill in Pannur was the Bashyam rice mill. The first modern rice mill was established by Shr. Malapati Sebastian Naidu called MSN rice mill. These rice mills helped the villagers who had agriculture as their prime source of income.

Pannur is located on the state highway connecting Thiruvallur and Kanchipuram.

Agriculture was the main source of income until the 1960s. Thereafter, many youngsters with better educational facilities began working as teachers or joined government services. From the 1990s, many youngsters acquired professional degrees, engineering degrees, medicine and joined leading software and corporate companies and hospitals. They migrated to cities such as Chennai, Hyderabad, Bangalore, Mumbai, Baroda, Delhi, etc., and many migrated to the US, UK, Australia, Ireland, Dubai, Middle East, Switzerland, France, Netherlands, Canada, Germany, and Singapore.
