Communion in Numbers
This is not a count of parishes, but of people — a fuller demographic reckoning of the Church's global communion: its worldwide population, its distribution across the fourteen districts of Kerala, and the diaspora it has sent out across the globe.
1901 to the present, modelled decade by decade.
The chart below is a constructed model, not a census: it stitches together the Church's own historical decade markers into a single continuous estimate, to show the shape of the story rather than an exact count for any one year. Early growth was steady and fast; by the 1990s it had visibly slowed; the worldwide total is now, on this model, past its peak and easing into decline.
The heartland of the Church, district by district.
Schismatics currently make up roughly a quarter of the Church, concentrated in the Ernakulam district (Angamaly, Kandanad East, and Kochi dioceses) and in pockets of central Thrissur (Thrissur diocese) and Kottayam. Since the Malabar migration, the main Jacobite population outside these areas is in Wayanad (Sulthan Bathery diocese). Knanaya Jacobites, on the other hand, are concentrated around three principal towns — Chingavanam (Kottayam), Ranni (Pathanamthitta), and Kallissery (Alappuzha) — though their pro-cathedral is located in Kottayam town.
Each bar shows the Malankara Orthodox share of that district's total population — that is, the proportion of everyone living there who belongs to the Church. Rank marks the community's standing among all Christian denominations present in the district; 1st means Orthodox is the largest Christian community there.
These figures are overwhelmingly marriages of one kind: an Orthodox man takes a wife from another denomination, and it is she who converts into the Church, rather than the reverse. Marthoma Protestants make up by far the largest share of these converts, not by chance but by geography — the districts where Orthodox Christians are most concentrated, namely Pathanamthitta, Alappuzha, and Kollam, are the same southern districts where Marthoma Protestants are also predominant, the two communities having lived side by side since their nineteenth-century split. Malankara Orthodox settlement in Kerala has traditionally been described as running from the village of Chathannoor in the south to Chalissery in the north — that is, from Kollam district up through Palakkad. Shown below is the share of converts by the denomination they came from.
Conversions arising from marriage to communities outside this list — such as Pentecostal churches — are negligible: in nearly every such intermarriage, it is the Orthodox spouse who converts to Pentecostalism, rather than the reverse.
A modelled accounting of departures, by decade.
The character of departure has changed twice over. In the mid-twentieth century, most who left did so for the Malankara Catholic Church. From the 1970s onward, Pentecostal churches drew the largest share. In the last two decades, the largest single category is no longer another church at all — it is leaving religious practice altogether. Conversions in, shown as the line below, have never come close to keeping pace with departures.
A figure of 493,858 Malankara Orthodox members in Kerala is often cited online as having come from the 2011 Census of India. This is not accurate. The official Census of India categorises respondents only under the broad umbrella of "Christianity" and does not collect or publish data on individual Christian denominations such as the Malankara Orthodox Syrian Church.
The figure instead appears to originate from independent socio-economic sample surveys — such as the Kerala Migration Survey conducted by the Centre for Development Studies (CDS) — in which researchers took small sample sizes, calculated the share belonging to each denomination within that sample, and mathematically extrapolated those percentages against the official 2011 Census totals for Kerala's Christian population. Many media articles have since mistakenly reported these calculated estimates as official census figures, which has led to significant underestimates of the Church's true size.
A few other quiet sources of undercounting compound the problem. Across the southern regions of Malankara, where few neo-Jacobites live, many of our members refer to themselves by the historical name Yakoba — a term surveys have sometimes misread as an admission of belonging to the schismatic neo-Jacobite party. Members who record their denomination simply as "Malankara" or "Malankara Syrian" have likewise sometimes been folded into the Malankara Catholic count. And thousands of members of Dalit mission churches — such as those in Chingavanam and Vakathanam — are recorded only as "Dalit Christian," with no record that they are, denominationally, Malankara Orthodox.
These are Malankara Map's own compiled estimates for 2022, drawn from parish and diocesan reporting across Kerala's fourteen districts and the Church's worldwide dioceses. District population percentages are calculated against each district's total population. As with any population estimate of a large, dispersed community, exact figures shift year to year; this page is updated as better data becomes available.
