The Holocaust Encyclopedia (HE), which is hosted by the United States Holocaust Memorial and Museum, presents this list of Jewish Holocaust deaths.
Here is the footnote for ‘other’:

The following is HE’s vague explanation for how they got the numbers and an admission that they are just estimates.
HE also states, “As more documents come to light or as scholars arrive at a more precise understanding of the Holocaust, estimates of human losses may change”, to account for changes in the death tolls that have occurred throughout the years. However I do not think this is good enough of an explanation for the sheer magnitude of the changes as illustrated below. Notice how the count never gets bigger, only smaller. This indicates that the numbers were deliberately inflated for propaganda purposes. It is also interesting to note how only 5 of these camps have their own category in the HE chart.
Next HE states (again), “There is no single wartime document that contains the above cited estimates of Jewish deaths.” What they won’t tell you is no single wartime document that says anything about a plan to systematically exterminate and gas Jews. The comprehensive statistics from point 1 below also say nothing about a plan to systematically exterminate and gas Jews. Furthermore, these comprehensive statistics of Jews killed were in reference to partisans, not innocent civilians.

The cope for the lack of documents is stated in point 2. How do the orthodox Holocaust historians know that the Axis conveniently destroyed all incriminating documents and physical evidence? They don’t. The Holocaust promoters are working with the premise that the Holocaust happened, therefore if there were no documents or physical evidence to corroborate they must have been destroyed. Circular logic at it’s slimiest.
You cannot make 6 million people disappear off the face of the earth. Cremated bodies leave behind ashes and bone fragments. Cremations done on outdoor pryes leave behind both human ashes and wood ash. You can not make millions of pounds of ashes disappear. Where are the ashes? Where are the mass graves?
Back to Point 1 from above, it claims that comprehensive statistics of Jews killed began in 1942 and ’43 while Point 3 claims that no personnel were inclined or available to count Jewish deaths until the very end of the war, which was in 1945. So which one is it HE? Your very own website has an entry for the Sterbebücher. These were deaths recorded by the Nazis for the Auschwitz camp. The 46 volumes record the deaths of almost 69,000 prisoners who were registered in the camp and who died between July 29, 1941 and December 31, 1943. Was this an honest mistake, HE, or were you being deceitful? Either way your credibility takes another hit.
HE claims there’s no way to distinguish why the Germans killed civilians in the East. German records state that they were anti-partisan activities and since orthodox Holocaust historians take the death toll numbers in these reports at face value they must do the same for the rest of the content of the reports. They cope with this by stating that killings had a racist componet. Kinda like sharing the United States murder stats has a racist componet? Was it the Germans fault that partisans and Bolshevik agitators were overwhelmingly Jewish?
Counting victims is important. Like the victims of the Dresden terror firebombing which Holocaust promoters seek to minimize. What is also important is not falsifying the number of victims thereby destroying the hopes and dreams of those falsely accused. Efforts to name the Allied lies are important to restore the good name of the German people that the liars sought to destroy.
Where were the celebrations when it was announced that it turns out that some 2-3 million thought to have been heinously murdered in Auschwitz in fact had survived? Wasn’t that wonderful news? If you had honestly thought some dear relatives had suffered some horrible fate and then found out that they hadn’t, wouldn’t you fall to your knees in joy as at the return of a prodigal son? Questions that answer themselves.
