There are no precise records of the number of Jews at the time of the Exodus.
However Exodus 12:37, says 600,000 walking men plus children. In the census taken about a year after the Exodus, recorded at Numbers 1:2, 3, 45, 46, there were 603,550 males (20 years old and older) plus 22,000 male Levites over one month old (Numbers 2:32, 33; 3:39) So how many women would be with 600,000 men? How many children would there be in a typical Jewish family at that time? If all the men had one wife, that would make 1,200,000 adults. If each of the 600,000 families also had three young children with them, that would be 1,800,000 children. Of course, many Jewish families would have had more than three children. However, by the time of the Exodus, many of these children would be adults!
We can see that it gets very difficult to estimate how many Jews in total. If we take the arbitrary figure of 3 children accompanying each family, then, by adding all the children to all the adults we get 3,000,000 people, i.e. Jews that came out with Moses. In addition, though not asked in the question, there were many non-Jews who also came out of Egypt with the Jews, See Exodus 12:38.
