Footfall in Dublin city centre was down 28% in the week to last Sunday compared to the same period last year, according to new data released by DublinTown.
The lower numbers are a consequence of the restrictions put in place by the Government last week to combat the spread of the Covid-19 virus.
In Grafton Street, footfall was 34% lower, while in O'Connell Street there were 28% fewer people in the streets.
The hospitality industry laden area around South William Street was down 44%.
DublinTown says much of the decline can be attributed to large swathes of the 250,000 people who work in Dublin city centre now working from home.
The expectation is that the year-on-year decline will further increase this week because there are no St Patrick’s Day festivities taking place.
DublinTown has reiterated its call for specific supports to be introduced by the Government for retail businesses.
"While this drop was to be expected, they starkly illustrate the challenges facing businesses in the city," said Richard Guiney, CEO of DublinTown.
