We are standing in front of a three-floor apartment building in central Bengaluru. “Thirty-seven,” says Vijaya as she locates the building on the block map and shares the number from the map associated with the building. She folds the map and places it under the household listing booklet on her clipboard. Vijaya has been trained as an enumerator for the SEC survey and she and her husband, Mohan, who is the DEO, are getting ready to interview their first household of the afternoon. She opens the household listing booklet and flips through it until she reaches the three entries for building number 37. She locates the number associated with the ground floor unit and tells her husband, “148.” Mohan types the number into his handheld tablet. The tablet contains preloaded data from the NPR, a recently created government database for a system of national identification. A few seconds later the data for household 148 populates the screen. Mohan reads aloud the name of the head of household, “R.L. Suresh.” Vijaya nods to indicate that “R.L. Suresh” matches the handwritten entry for the head of household in the household listing booklet, which census enumerators created during the first round of Census 2011 two years earlier. Mohan opens the front gate, and we walk into the small compound and up to the front door of the ground-floor unit. Mohan knocks on the front door with his right hand and holds the tablet in his left hand. A few seconds later, a woman in her mid- to late thirties opens the door and looks at the three of us. Mohan holds up the handheld device as he explains that we are here “for census work.” He then asks, “Is this the house of R.L. Suresh?” The woman nods in acknowledgment. She invites us into the drawing room and asks us to sit. As we settle into chairs, she closes the front door and stands near the entrance. Her teenage son stands in a corner of the room and watches. Mohan confirms the name, sex, and age of the four household members based on preloaded NPR data.
