Business activity in Dublin continued to recover in the third quarter of the year, according to the IHS Markit Dublin Purchasing Managers Index (PMI).
The headline rate accelerated to 62.1 from 60.2 in the previous quarter, its highest level since 2014.
All three of the monitored sectors of construction, services and manufacturing posted substantial increases with the latter rising at its fastest rate in the more than twenty year series history.
The data shows that output across the rest of Ireland rose at a similarly sharp pace.
For the second consecutive month there was strong growth in new orders with the pace quickening to its fastest level since 2014.
Dublin companies also increased their staffing levels at the fastest rate since 2018.
This marks the third quarter in a row where companies in Dublin increased their staffing levels.
Employment expanded across the rest of Ireland at a similar rate to Dublin.
"The particularly steep growth rates we've seen since the economy reopened will likely prove unsustainable, especially given some of the supply constraints being felt by firms at present, but there’s no reason why companies shouldn’t settle into a solid and sustainable period of expansion as the year comes to an end," said Andrew Harker, Economics Director at IHS Markit.
