We examined the heliolatitude distribution and North-South (N-S) asymmetry of Ground Level Enhancement (GLE) event source locations from 1942 to 2024, finding distinct patterns between the periods 1942–1979 and 1980–2024. Between 1942 and 1979, 33 GLE events were recorded: 5 from the southern hemisphere within [S3, S11] and 28 from the northern hemisphere within [N7, N37]. The southeast quadrant was devoid of any source locations for GLE events. 45.4% of the source locations of the GLE events were within the latitudinal range of [S15, N15]. The remaining source locations of the GLE events were distributed at latitudes above 15° in the northern hemisphere. Between 1980 and 2024, 43 GLE events were recorded: 25 from the southern hemisphere and 18 from the northern hemisphere, with all events above 30° latitude originating from the northern hemisphere. Approximately 44.2% of the source locations of the GLE events were distributed within the latitudinal band [S15, N15]. Over the period from 1942 to 2024, 44.7% within [S15, N15], 63.2% within [S20, N20], 80.3% within [S25, N25], 88.2% within [S30, N30], and 11.8% at latitudes above 30°. N-S asymmetry was significant at latitudes above 0°, 5°, 10°, 15°, 20° and 30°, with northern hemisphere dominance. Moreover, a strong inverse correlation exists between the number of GLE events from the northern and southern hemispheres at latitudes above 0°, 5°, 10°, 15°, 20°, 25° and 30°.
