The Central Statistics Office has said that 38,700 Ukrainians have arrived in Ireland since the Russian invasion on 24 February.
The number has increased by just under 3,000 in the two weeks leading up to Sunday 19 June.
Women aged 20 and over account for 47% of the arrivals, while people under the age of 20 account for 37%.
Those in the largest group of arrivals - 41% or 15,850 individuals - are classified as "one parent with children".
As of 7 June, 6,890 Ukrainian children were enrolled in Irish schools; 71% of which were in primary school.
The figures come from a weekly Department of Social Protection report which includes the number of Ukrainians who have been given a PPS number and are availing of the Temporary Protection Directive.
This directive was activated by EU countries on 4 March to protect people displaced by the Russian invasion of Ukraine.
The figure is an estimate because some Ukrainians may have not received a PPS number yet or may no longer be in Ireland.
However, experimental data from the CSO shows 89% of those aged over 18 were "administratively active" in the State after 15 May.
The CSO was also able to map 91% of arrivals to a local post office address.
A total of 1,245 Ukrainian arrivals have been mapped to Dublin's north inner city, while the local electoral area with the highest proportion of Ukrainian arrivals compared to its population was Ennistymon in Co Clare, at a rate of 7.28%.
