The Lok Sabha can remove a government; the Rajya Sabha cannot. That constitutional difference suggests different incentives, but the questions record shows more overlap than separation.
Only four of fifteen broad subject groups leaned clearly toward the Rajya Sabha. Most subjects were distributed more evenly, suggesting that constituency pressure, party strategy, and committee work can matter as much as the formal powers of each House.
Where the split appears
The useful comparison is not a single percentage. It is the combination of subject, question type, member, and ministry. Together, those fields reveal where one House is developing a distinctive agenda—and where both are following the same public pressure.
