North 24 Parganas: A District of Ten Million and the Diagnostic Gap

North 24 Parganas is the most populous district in India. Around 10.9 million people live here, a number close to the entire population of Bolivia. Barasat, where our centre sits, is the district headquarters and a junction town — rail and road lines run through it, which is part of why it became a hub for the blocks around it.

The size is the first thing people notice. The second thing, if you work in health here, is how unevenly the infrastructure is spread across it.

The numbers behind the gap

The district runs a tiered public health system, and on paper the structure is there. In practice, the rural and peri-urban blocks carry a load the facilities were never sized for.

Take Amdanga, one of the blocks in our outreach reach. Its rural hospital has roughly 60 beds for a population near 192,000. A third of households there live below the poverty line, above the district average. A majority of the population is from a minority community that has historically faced extra barriers to care. The arithmetic does not need commentary — 60 beds, 192,000 people.

Barasat II block is overwhelmingly rural, with the vast majority of its 200,000 residents living in villages. Barasat I is around 60% rural. Across these blocks the same study of district health infrastructure found wide variation between urban and rural sectors, with the rural blocks bearing the largest gaps.

What "gap" means day to day

A gap in infrastructure is an abstraction until you watch how it plays out. It means a specialist diagnostic test that exists in Kolkata or at the district medical college, but might as well be on the moon for a woman two bus changes away with a day of work to lose. It means screening that technically is available but practically is not.

The immediate population within reach of our hub-and-spoke approach — Barasat town plus the Barasat I, Barasat II, and Amdanga blocks — comes to more than 700,000 people. The majority are rural or semi-urban, lower-income, and, among the women, facing an anaemia burden well above 70%.

Why we are based here

We did not pick Barasat because it is easy. We are based here because the need is concentrated and the access is thin, and because a trusted local diagnostic centre is exactly the kind of anchor a hub-and-spoke model needs. The same access barriers that define this district — agricultural poverty, low literacy, thin primary care, distance — are the ones that define underserved primary-care settings far beyond West Bengal. Get the model right here, and it travels.

That is the work: take a district where the diagnostic gap is as wide as the population is large, and start closing it one screening at a time.
