This is an interesting question because it's all about how to count.
I have made a list of all crewmembers on the Kes Website (link below). They also include characters mentioned in the Voyager books and names on screen lists. However, there are some questions about how to count them. As I've written on the site:
There are still some interesting things here. First of all, the list includes 218 names. If we omit the Maquis members (31 total including 11 characters mentioned in books) and characters who came on board after Voyager's arriveal to the Delta Quadrant, such as Kes, Neelix, Naomi Wildman and later additions such as Seven Of Nine, The Equinox crew and such, we'll discover that Voyager, when it arrived in the Delta Quadrant, had 184 Starfleet crew members, not 141 which is the official number. These numbers include Tom Paris and Tuvok but not The Doctor since he wasn't regarded as a Starfleet crewman when the ship arrived in the Delta Quadrant.
However, if we omit the characters mentioned in the Voyager books, (65 characters total) then we can bring down the Starfleet personnel to 119 which is more acceptable. If we omit the crewmembers whose names were visible on lists in alternate universe or dream sequence episodes like "Non Sequitur" and "Projections" (32 crewmembers) we are down to 87 names.
If we omit the crewmembers whose names were visible on lists in alternate universe or dream sequence episodes like "Non Sequitur" and "Projections" (32 crewmembers) but add the crewmembers mentioned in books, we will have total 186 crewmembers. If we omit the Maquis (31 total including 11 characters mentioned in books) plus Kes, Neelix and Naomi Wildman, we will be down to 152 Starfleet crewmembers when Voyager arrived in the Delta Quadrant.
However, there is also another way to explain the inconsistences.
Let us assume that Voyager actually had two missions.
The first one was to find Chakotay's Maquis ship.
But the other was to establish a bridgehead in the badlands which would be used for an invasion of the area in order to conquer the Maquis. Therefore a Special Force were also on board to establish such a bridgehead on one of the planets in the badlands. That Special Force had 43 members.
So what Voyager had from the start was 141 crew members (including Tuvok and Paris) plus 43 members of the Special Force led by Lt. Cavit then we have 184 crew members when Voyager arrived in the Delta Quadrant.
When Voyager became stuck in the Delta Quadrant and Cavit died, the "Badlands mission" was simply forgotten and no one talked about it anymore, except maybe Janeway, Chakotay and Tuvok in some internal conversations in Janeway's ready room. The members of the Special Force were just incorporated in the Voyager crew.
Full crew list is to be found on the
Kes Website under the link Crew list in the left column of the site.
Note that I hadn't seen
Akiraprise's link to the Ex Astris Scientia page when I wrote my comments above. I might have to do some corrections on the list on the Kes Website in the near future.
