At last: Estimate for Chabad in the US!!! #ChabadUSA #ChabadStatistics #ChabadSociology

In a previous post, we’ve speculated that the population size of Chabad in the United States could be calculated by working backwards, starting from the number of students in Chabad day schools, and multiplying that number by the average household size.

Well, in this post, we’ve estimated the number of students in Chabad day schools (whom we assume are being raised in Chabad homes) at 12,296. And in this post, we’ve reported that the average household size and other figures in the Montreal Chabad community. If we assume that the demographic profiles of Chabad in Montreal and that of Chabad in the US match each other, the formula to estimate the size of Chabad in the Unted States would be:

•The number of schoolchildren divided by the number of households with children equals the number of US Chabad households with children.
•The number of households with children times the average household size (for households with children) equals the number if persons in households with children
•The number of households with children times itself plus percentage of childless households equals the total number of US Chabad households
•The number of total households times the average household size (for all households) equals the total number of persons in US in Chabad households.

So there you have it!!! An formula for estimating for Chabad in the United States.

And here’s the numbers…

Schoolchildren to households
12,296 Children in US Chabad Day School
4.63 Mean number of children per non-childless household (Montreal)
2,655.72 Mean number of US households with children (12,296/4.63)
6.67 Mean size of household with children (Montreal)
17,713.68 Mean number of US households with children times mean size (2,655.72*6.67)
5,417.68 Adults and others members of household not in school (17,713.68-12,296)
2.04 Average number of persons per US household not in school (5,417.68/2,255.72)
Households continued
22% Percentage of (total) households with no children at home (Montreal)
47% Percentage of childless households with only one occupant (Montreal)
3,239.98 Mean US households, both with and without children (2,655.72*1.22)
584.26 US households without children (3,239.98-2,655.72)
274.60 US households with one occupant (584.26*0.47)
309.66 US households with no children but with two (or more) occupants (584.26-274.60)
17,713.68 Number of persons in all households with children
>619.31 Number of persons in childless households with two occupants or more (309.66*(>2))
274.60 Number of persons in childless households with one occupant
>18,607.59 Total number of persons in US Chabad households

Is it possible to estimate size of Chabad in the US? #Chabad #Statistics #ChabadSociology


Chabad estimates vary a great deal. It is often reported that Chabad members number some 200,000.

Samuel Heilman has estimated Chabad at around 40,000. But even he is unsure whether or not to count the Jews who have joined the many Chabad centers across the globe as members of the Chabad movement proper.

Heilman’s figure might not be that far off. But suppose we could get a solid estimate for Chabad in the US using Jewish day school figures?

In the US, there are around 13,000 students in Chabad day schools. Jewish day school education is pretty much the standard among US Orthodox Jews. So it is reasonable to assume that these students are from Chabad homes.

If this is so, suppose we try calculating based on this figure? All we would need is the number of children per Chabad home. Working backwards, we might be able to get a safe estimate for the number of Chabad Jews in the US.

Chabad of Montreal: Here’s the stats!!! #chabad #montreal #chabadsociology


In 2003, a study conducted in Montreal took a census of the ultra Orthodox in Montreal. Included in the reapondenta of that study, were 287 Chabad households (in this case, respondents self-identified as Chabad).

While the study was conducted a decade ago, it is the most current data on this community. So here’s what we know about Chabad in Montreal:

Total households
•There are around 287 households that identify as Chabad.
•Chabad households make up 13% of the ultra Orthodox community (there are an estimated 2,193 ultra Orthodox households), and 0.6% of the total Jewish population in Montreal (there are an estimated 41,125 Jewish households). Note that the general Jewish population has fewer persons per household.

Number of people
•The estimated number of persons living in Chabad households is 1,590 (the mean size of Chabad households is 5.54, and 6.67 when excluding childless households).

The number of persons per household varies:
•10.5% have 1 person (30 households in total)
•39.9% have 2-5 persons (114 households)
•39.2% have 6-9 persons (112 households)
•10.5% have 10+ persons (30 households)

•The estimated number of children living in Chabad households is 1,038 (the mean number per Chabad household is 3.62, and 4.63 when excluding childless households).

The number of children varies per household:
•9.9% have 1 child (22 households in total)
•58.3% have 2-5 children (130 households)
•26.6% have 6-9 children (59 households)
•5.4% have 10+ children (12 households)

Fertility rate
•The fertility rate among Chabad women of Montreal is estimated at 5.06.

•The mean age is 22.46.

Here’s a breakdown by age group:
•45.8% are aged 0-14 (712 persons in total)
•20.9% are 15-24 (324 persons)
•17.1% are 25-44 (266 persons)
•12.1% are 45-64 (188 persons)
•1.9% are 65-74 (30 persons)
•2.1% are 75+ (33 persons)

Ethnic background (Sephardi/Ashkenazi
•Of the 526 respondents and spouses, 94 (17.9%) identified as Sephardi, and 432 (82.1%) as Ashkenazi.


Shahar, Charles. “Main Report: A Comprehensive Study of the Ultra Orthodox Community of Greater Montreal (2003)”. Federation CJA (Montreal). (2003): pp. 7-33.’s Hasidology blog creates a platform for Chasidic academia #Hasidology #ChabadSociologist


Recently, has had the opportunity to surprise the public as to what a Chasidic website can offer the world. Rarely, it seems, does the flagship site of the Chabad-Lubavitch movement pass up on the chance to produce the insightful and cutting-edge type of content the Jewish world needs.

One such project is the “Hasidology blog”. Run by writer and researcher Eli Rubin, this blog tackles topics in Chasidic thought and history with keen eye. Chabad concepts are explained, and Chasidic history is unearthed. This content is both unique and of fine quality. The best part, it seems, is that it’s online for everyone to view, comment and share.

Check out the Hasidology blog here! It’s defiantly worth the while.

Chabad Scholar Questions Penal System Methods #Prison #Ethics #ChabadSociologist


At the recent Jewish Law Symposium, sponsored by Chabad of Southeast Morris County, Chabad scholar, Rabbi Shlomo Yaffe, raised some of his concerns with the US penal system. Basing himself on traditional Jewish teachings, Jaffe pointed to the ethical issues surrounding contemporary forms of incarceration. Disparities in sentencing for minorities and lengthy sentences for minor or first-time offenses are often antithetical to Jewish notions of restitution and rehabilitation.

Yaffe supports alternative sentencing and rehabilitation programs for nonviolent offenders.

Find out more about the US prison system at the BOP website, and on Wikipedia.

Rabbi Shlomo Yaffe is the dean of the Institute of American and Talmudic Law, a division of Chabad Lubavitch of Midtown Manhattan. Check out the original article here!

Google Glass Documentary in Crown Heights by local Blacks and Jews #project2x1 #ChabadSociologist #GoogleGlass


The Chabad community in Crown Heights, Brooklyn has been the focus of studies on Black-Jewish relations (see for example, “Race and Religion Among the Chosen People of Crown Heights” by Henry Goldschmidt (Rutgers University Press, 2006)). But recently, some locals are attempting to do their own research. They’re doing a documentary using… Google Glass!

The project is called #project2x1. Here’s a bit from their Facebook face:

Project 2×1 is a short documentary film shot on Google Glass, exploring the cultures of the Hasidic and West Indian communities of Crown Heights—a 2 mile long x 1 mile wide neighborhood of Brooklyn. The story tests the limits of Google Glass, the world’s newest and most intimate filmmaking device, by developing a truly collaborative narrative told through the eyes of as many community members as possible, capturing each community’s rituals and routines, their similarities and unique differences.

Project 2×1 was launched with both a local and universal mission. In Crown Heights, we aim to facilitate more inter-community dialogue and grassroots, community development. Our broader mission is to spark a universal movement combating the “neighborhood anonymity epidemic” and encourage more people to tell the stories of their own neighborhoods.
