Auschwitz in Numbers

Numbers on this scale go numb — the mind quietly rounds a million down to "a lot." Every figure below is one the museums and state archives have documented and can trace to its source. Behind each is one person, and then the next, and then the next.

Of everyone murdered at Auschwitz, about nine in ten were Jews.

The camp was, above all, an instrument for the destruction of the Jewish people. Others were murdered here too — Poles, Roma and Sinti, Soviet prisoners of war — but that nine in ten of the dead were Jews is the fact the whole history turns on.src

Five years, one arc

Auschwitz did not kill at a steady rate. The chart below plots the average number of Jews deported here per month — low through 1942 and 1943, then a vertical spike in the summer of 1944, when about 420,000 Hungarian Jews were deported in under eight weeks. That is nearly 215,000 a month — some nine times the 1943 pace. Every figure is drawn from the museums' documented totals; hover any point to open the moment it marks.

How to read this graph: each point is the average number of Jews deported to Auschwitz per month during that period, worked out from documented yearly and event totals. The Nazis never kept a running monthly count, so every figure is an estimate — historians' numbers can differ by roughly ten percent or more. The most authoritative source is the Auschwitz-Birkenau State Museum, whose demographic research (Dr. Franciszek Piper) established the roughly 1.1 million people murdered here, about one million of them Jews; per-year figures are cross-checked against the USHMM. (The Auschwitz Museum puts the 1942 figure at about 197,000; the months just before the 1944 Hungarian deportations are not broken out in the yearly totals, and are left faded.)

The History

What Was Auschwitz?

Auschwitz was the largest of the Nazi concentration and extermination camps — not one site but a complex in German-occupied Poland, where roughly 1.1 million people were murdered, about one million of them Jews.

Established in 1940 near the town of Oświęcim, the complex grew into three principal parts. Auschwitz I, the original main camp. Auschwitz II–Birkenau, begun in late 1941 and expanded into 1944, became the largest killing center of the Holocaust, with four gas chamber–crematorium complexes. Auschwitz III–Monowitz supplied slave labor to the IG Farben works, alongside dozens of subcamps.

Those murdered included Jews deported from across Europe, Polish political prisoners, Roma and Sinti, and Soviet prisoners of war. Jews were the overwhelming majority of the dead.

The Sonderkommando & the Four Photographs

In the summer of 1944, a prisoner hid a camera and photographed the killing as it happened. These are among the only images of the murder process made by its victims.

The Sonderkommando were Jewish prisoners forced, under threat of death, to work in and around the gas chambers and crematoria. They witnessed everything — and some risked everything to leave a record. Project Witness has told that record in film.

The People

Diaries That Ended at Auschwitz

Some of the most extraordinary writing of the twentieth century was done by teenagers whose diaries lead to Auschwitz. Their notebooks outlived them.

The Centerpiece · Rywka Lipszyc

Rywka Lipszyc was fourteen when she began a diary in the Łódź Ghetto. Deported to Auschwitz-Birkenau in August 1944, she left the notebook behind — and in June 1945 a Red Army physician, Dr. Zinaida Berezovskaya, found it in the ruins beside Crematorium III and carried it home to Siberia.

Rywka herself survived Auschwitz, a labor camp, and a death march to Bergen-Belsen; her last trace is a displaced-persons record dated 10 September 1945, noting her transfer that July to a hospital in Niendorf, Germany; then the record ends. Her words outlived the trail of her own life.

Cover of the published book Rywka's Diary: The Writings of a Jewish Girl from the Lodz Ghetto
The found diary

Berezovskaya kept the notebook at her home in Omsk, Siberia, until her death in 1983; her granddaughter found it among the family's belongings in Moscow in 1995. It reached the JFCS Holocaust Center in San Francisco in 2008 and was finally published in 2014 — a schoolgirl's diary, retrieved from beside a crematorium, that took seventy years to be read.

She kept a diary from 1940 to 1942 — a young life narrowing under occupation. Deported to Auschwitz and murdered there, still in her teens. Her diary survived and was published — one more voice the murderers could not silence.

Deportation: The Destruction of Hungarian Jewry

In the spring and summer of 1944, in a matter of weeks, some 430,000 Hungarian Jews were deported to Auschwitz, the largest deportation in the camp's history and its deadliest period. Most were murdered on arrival.

The Cattle Car

Before Auschwitz there was the journey to it — sealed for days inside a freight wagon built for goods and livestock. The car was not incidental to the crime. It was an instrument of it.

"[I]t was a cattle car as you know, no windows, had no seats and no toilet. … We honestly thought we were going to be relocated, until the door closed and we heard the lock go on from the outside."Fritzie Weiss Fritzshall, describing her deportation to Auschwitz in 1944. USHMM oral history.
Project Witness's own 3D model of a covered goods wagon (Güterwagen), restored from PW's History of Antisemitism curriculum. Drag to rotate, scroll to zoom, and open the sliding door to see inside.

Ordinary freight cars, not purpose-built. Deportation trains in Eastern Europe typically used covered goods wagons — the German covered goods wagon (Güterwagen), a type built by the tens of thousands between 1910 and 1927.src

Commonly 80 to 100 people were forced in, and more than 100 in the most crowded transports. In practice that floor of roughly 21 m² held about eighty people, and at times more than a hundred. The cars were sealed and locked from the outside, with one bucket for sanitation and no food or water. Transports lasted days, and many died before arrival.src

The deportees were charged for their own deportation. Historian Raul Hilberg documented that the Reichsbahn billed the SS a per-head group fare — the price of a one-way third-class ticket, about 4 Pfennig per track-kilometer, half-price for children under ten, with a bulk discount for trainloads of 400 or more. People treated as cargo were counted, and billed, as passengers.src

Built for goods and livestock; at Auschwitz, about eighty people were forced into a single car.
Each figure is one person, drawn to scale on the same wagon floor — a covered goods wagon roughly 8 × 2.7 m (21 m²), which holds about eighty shoulder to shoulder. Past that, people stood pressed against, and often on top of, those already there.

Faith under annihilation

Faith in the Camps: Spiritual Resistance

Secret minyanim. Hidden tefillin. Halachic questions asked inside the camp and after liberation. This is the story of the Jewish soul under annihilation — told, from within the tradition, as a first-class chapter of the history.

Inside Auschwitz, religious observance was forbidden and dangerous, and some Jews kept it anyway. Joseph Sander, whose testimony is above, kept his tefillin hidden through Auschwitz and put them on in secret on the morning of his bar mitzvah. The Nazis set out to destroy not only a people but a way of life. That any of it survived is its own form of resistance.

And faith did not end at liberation — it met its hardest questions there. How does a survivor mourn the unburied, remarry when a spouse's death cannot be proven, or believe again at all? Project Witness tells this story from within the tradition, where it was lived.

The perpetrators, at leisure

The Höcker Album

In 1944, at the height of the murder of Hungary's Jews, an SS officer named Karl Höcker filled a personal album with photographs of Auschwitz's staff at leisure — singing, relaxing, eating blueberries at a country retreat called Solahütte, about 30 km (20 miles) from the gas chambers they operated. The album survived. It is one of the most disquieting documents of the Holocaust: the ordinary, smiling faces of people who had just overseen the murder of some 330,000 Hungarian Jews in eight weeks.

The History

Liberation & Memory

As Soviet forces advanced in January 1945, the SS forced tens of thousands of prisoners on death marches westward. On 27 January 1945, the Red Army entered Auschwitz and found some 7,000 survivors, along with the evidence the Nazis had failed to destroy. That date is now International Holocaust Remembrance Day.

Memory is not only commemoration — it is testimony kept watchable, and history kept accurate. That is the work of this archive.

Free, Classroom-Ready

Every testimony and film above is free to stream — no login. Bring survivor voices into your classroom, and start with questions that matter.

  • Why did the Sonderkommando risk their lives to photograph the killing? What does it mean to leave a record when you do not expect to survive?
  • Rywka's diary was found beside a crematorium and read seventy years later. What does it mean for words to outlive the person who wrote them?
  • The Hungarian Jews were deported in 1944, when Germany was already losing the war. What does that reveal about the Holocaust as a goal in itself?
