Must Know Terms :

 

1.CMMS

CMMS stands for Census Management and Monitoring System, a dedicated portal developed for Census 2027. It enables near real-time monitoring of the entire census process through integrated dashboards. Officers at sub-district, district, state, and national levels can track field progress, operational readiness, and performance. The portal is central to digital coordination, supervision, and timely implementation of India’s first digital census.

2. SelfEnumeration

SelfEnumeration is an optional citizen facility introduced for Census 2027 through a secure online portal. It allows eligible household respondents to submit information independently before the enumerator’s visit. After successful submission, the system generates a unique Self-Enumeration ID for verification. The facility is available in 16 languages and includes user guides, validation checks, tool tips, FAQs, and tutorial videos inside.

3. CensusAct

CensusAct refers to the Census Act, 1948, which provides the legal basis for conducting the population census in India. It works with the Census Rules, 1990, within a centrally coordinated framework because census is a Union subject. A major protection under Section 15 keeps personal information confidential, strictly barring disclosure under RTI, court use, or institutional sharing of individual data.

5. HLBC

HLBC stands for Houselisting Block Creator, a web mapping application to be used by Charge Officers in Census 2027. It helps create digital Houselisting Blocks using satellite imagery, improving geographic precision and coverage. The application aims to prevent omission and duplication during enumeration by ensuring that every census block is accurately identified, mapped, and assigned before field operations begin nationwide.

6.CII

CII stands for Critical Information Infrastructure, the designation given to the secure data centres hosting Census 2027 data. This status ensures heightened protection for collection, transmission, and storage systems. The security framework includes end-to-end encryption, secure transmission protocols, and compliance with ISO/IEC 27001:2022 standards. Regular audits by reputed agencies further strengthen confidentiality, resilience, and data integrity across all census operations.
