The veteran Gandhian said he has been writing to Prime Minister Narendra Modi on these issues but hasn't received a response.
"At least 12 lakh farmers have committed suicide in the last 22 years. I want to know the number of industrialists committing suicide during this period," he said.
Hazare has been demanding the formation of Jan Lokpal to keep a check on corruption.
He went on a 12-day hunger strike in 2011 after which the then United Progressive Alliance (UPA) government accepted the demand in principle.
Hazare later launched a fast, which enjoyed a huge popular support across the country. The UPA government later passed the Lokpal bill.
An aide of Hazare today said the Modi government has not appointed a lokpal. "The reason given from the government's side is technical," he said.
He said according to the Lokpal Act, a committee comprising the prime minister, the Lok Sabha speaker, the leader of opposition in the Lok Sabha and the chief justice of India or a Supreme Court judge nominated by him, should be formed and select the Lokpal.
"However, as there is no leader of opposition in Lok Sabha at present, the committee could not be formed and the lokpal could not be appointed," the aide said.
The central government cited the same reason in an affidavit it filed in the Supreme Court when replying to a public interest litigation, he added.
