St Andrew North Western was created in 1976 when the number of constituencies was increased from 53 to 60. The parish of St Andrew was granted three additional seats moving from eight to 11.
The constituency is bounded from a point where Washington Boulevard crosses the Sandy Gully at the bridge, easterly along the northern side of Washington Boulevard to the Rochester Gully, north easterly along the western and northern sides of this gully to Red Hills Road, northerly along the western side of Red Hills Road to the Constant Spring Gully, then easterly along the northern side of the Constant Spring Gully to Mannings Hill Road. It then goes northerly and easterly along the western and southern sides of Mannings Hill Road to a point opposite the end of Westmead, thence, south easterly in a straight line to Westmead, south easterly along the northern side of Westmead (so as to include all premises on Westmead) to a point opposite Montcalm Drive. From there it goes southerly in a straight line to Montcalm Drive along both sides of Montcalm Drive to its end (so as to include all premises on Montcalm Drive), easterly along the southern boundary of Chancery Hall property to Michigan Avenue, southerly along the eastern side of Michigan Avenue to where it meets Sunbridge Gully. It then travels westerly along the foothills of the Duhaney Park-Patrick City gully along the gully to Waterhouse Drive, south westerly on the eastern side of Waterhouse Drive to Washington Boulevard, easterly along the northern side of Washington Boulevard to the starting point.
Electoral divisions in the constituency are Chancery Hall, Havendale and Hughenden.
Of the eight contested parliamentary general elections, the Jamaica Labour Party has won seven to the People’s National Party’s one. In 1976, Dr Kenneth McNeill (PNP) defeated Karl Samuda (JLP) 6,611 votes to 4,743. In 1980 Samuda sent Carlyle Dunkley into early retirement from representative politics when he trounced him by a massive 5,646 majority.
With Samuda shifting to the St Andrew North Central seat in 1989, Derrick Smith stepped in to fill the breach for the JLP. In a very close contest, Smith beat the PNP’s Dr Jephthah Ford by 233 votes and remains undefeated.
