Delhi was supposed to be the success story. A dense, relatively prosperous metropolis with functioning public health infrastructure, a literate female population, and decades of family planning investment behind it. The National Family Health Survey-6, released for 2023-24, punctures that narrative with a single, stark number: the share of currently married women aged 15 to 49 using any family planning method — modern or traditional — dropped from 76.4 percent in the 2019-21 survey cycle to 67.4 percent. That is not a marginal statistical flutter. That is nearly one in ten women who had some form of coverage losing it.

The decline cuts across every category the NFHS-6 tracks. Use of any modern method — which the survey defines to include the full range of clinical contraceptives, not just the headline sterilization and IUD figures — fell from 57.7 percent to 51.2 percent. Traditional methods, which include periodic abstinence and withdrawal and were already considered an imperfect buffer, dropped from 18.7 percent to 16.2 percent. Together, those two slides represent a systemic retreat, not a one-method anomaly.

What makes the numbers more damning is the companion metric: unmet need is rising. Unmet need — the proportion of women who want to avoid or delay pregnancy but are not using any method — is the indicator that exposes the gap between stated desire and actual access. When contraceptive prevalence falls while unmet need climbs, the policy interpretation is unambiguous: demand has not softened. Supply, reach, or both have failed.

The COVID-19 pandemic is the first alibi that health officials will offer, and it deserves partial credit. The 2019-21 baseline captured a period of severe disruption to primary health services across India, which should, if anything, have made the following years look like a recovery. They did not. Whatever momentum the public health system was supposed to rebuild after 2021 apparently did not reach the communities that showed up in this data. The post-pandemic rebound that appeared in other health indicators has not materialized here.

There is also a structural story beneath the pandemic excuse. Delhi's public health delivery for family planning has long relied heavily on female sterilization — tubectomy — as its primary modern method. That overreliance has been documented across NFHS cycles and by the office of the Registrar General. When sterilization rates plateau or dip, as they have nationally amid shifting demographics and some community-level resistance to permanent methods, systems that never adequately built up spacing-method infrastructure — IUDs, injectables, oral pills distributed through community health workers — have no fallback. The result is the drop now visible in the data.

The male contribution is, as ever, negligible. Male condom use has never carried significant weight in Delhi's contraceptive prevalence figures, and vasectomy rates remain in low single digits nationally and locally. The NFHS-6 data, consistent with every prior cycle, reflects a system that has placed the entire contraceptive burden on women's bodies and women's access to facilities, then expressed surprise when that single-threaded system frays.

There is a political dimension that the official fact sheet does not name. Delhi has been a contested administrative space — with the elected state government and the central government having overlapping and frequently conflicting jurisdiction over health departments, Mohalla Clinics, and ASHAs. Resource allocation disputes, staff deployment freeze-outs, and the long-running tussle over the National Capital Territory's governance structure have real downstream effects on whether a community health worker shows up consistently in a resettlement colony in Bawana or a JJ cluster in South-East district. The NFHS cannot capture governance dysfunction in its tables, but anyone who has reported on Delhi's health system recognizes the fingerprints.

What the NFHS-6 cannot yet tell us — because the granular district-level breakdowns are still being processed — is which pockets of Delhi are driving the aggregate fall. Aggregate city numbers can mask enormous internal variation: South Delhi's planned residential colonies and North-East Delhi's dense migrant-heavy settlements are not the same healthcare universe. Understanding whether this is a concentrated failure in specific sub-populations or a broad-based erosion will determine whether the corrective response needs to be targeted or systemic. On current evidence, the burden of proof rests with anyone arguing it is not both.
