The number of people receiving unemployment assistance in Massachusetts dipped a mere 1.8 percent last week despite the impending start of another phase of the state’s economic reopening plan.

Continued unemployment insurance claims stood at 548,441 as of June 27, the Executive Office of Labor and Workforce Development said Thursday, down only 9,828 from the previous week. That figure is still over 243,000 higher than the state’s highest number of unemployed during the Great Recession.

Construction workers represent the single-biggest source of continued unemployment claims, at 28.4 percent of the total, followed by food and hotel workers at 19.1 percent, healthcare and social assistance workers at 13.4 percent and retail workers at 12.5 percent.

Massachusetts had 29,072 people file an initial claim for regular unemployment insurance between June 21 and June 27, a drop of only 469 from the previous week and the third consecutive week of decline. However, increases were seen in filings from workers employed in public administration and education as school systems formally closed for the summer. Initial claims in the state’s Pandemic Unemployment Assistance system for freelancers and other contract workers filed for the week ending June 27 stood at at 14,154, slightly more than the previous week.

The state also noted that 59,144 people have filed for 13 extra weeks of unemployment benefits since May 21, when a special extension program was set up, indicating many who lost their jobs at the beginning of the coronavirus crisis have been unable to find work.
