Puerto Rico's economic activity index climbed 0.1% in November compared to October.
Compared to November 2013 the November 2014 index value was down 2.1%.
Compared to October, non-farm payroll employment and gasoline consumption were up and electric power generation and cement sales were down.
Total non-farm payroll employment increased 1.2% compared to October and was essentially unchanged from the year-earlier level, the Government Development Bank for Puerto Rico reported. Seasonally adjusted non-farm employment had its fourth consecutive increase from the year-earlier level.
Private sector employment had its 13th consecutive monthly increase from year-earlier levels.
Gasoline consumption increased by 2.8% compared to October and by 1.3% compared to November 2013.
However, electric power generation decreased 11.2% from October and 3.3% compared to November 2013.
Puerto Rico's cement sales decreased 24% compared to October and 19.5% compared to November 2013.
Despite these major decreases in cement sales, the United States Bureau of Labor Statistics drew a different picture of the direction of the island's construction industry.
From October to November the island's seasonally-adjusted mining, logging and construction employment was down 0.3%. From November 2013 to November 2014 it was up 7.6%.
The GDB says its economic activity index has historically had a strong positive correlation to Puerto Rico's Gross National Product both in level and growth rates.
