The 68000 architecture was much more flexible than other CPU families (z80, 80x86, z80000, etc) from programming point of view as it could be easily expanded to support full 32-bit data and address buses. This was done in Motorola 68020 family.

So even though starting out as "16-bit" cpu, the 68000 instruction set describes a 32-bit architecture. ... The Motorola 68000 is a CISC microprocessor, the first member of a successful family of microprocessors from Motorola, which were all mostly software compatible. The entire series was often referred to as the m68k,
