If you're asking what % of the modern Irish population is of English descent, Danish descent, and so forth, here's a good place to start: http://www.eupedia.com/forum/showthread.php?24907-Genetics-of-the-British-and-Irish-people
But since much of the information is of a technical sort, (requiring a fair grounding in the language of human genetics), it'd take quite a bit of study and a fair amount of number crunching to nail down percentages across various lineages.
An estimate is however given which states that roughly one quarter of today's Irish population descends from English stock (paternally). We'll understand how necessarily 'approximate' this has to be because, of course, what it means to be English is itself up for grabs as, yes, they too are an amalgam of peoples in their own right.
Based on the presence or absence of specific genetic markers, (and groups of markers, really), great gains are apparently being made toward clearing all of this up though. So the day may soon come that such questions can be answered with greater ease and confidence.

In 1971 Ireland was:
99.1% White
0.4% Black
0.3% Asian
0.2% Other/Mixed
In 2001 Ireland was plus the TFR:
97.9% White; 2.27
1.4% Asian; 1.57
0.3% Black; 3.33
0.4% Other/Mixed; 1.90
Now 11 years later....
Ireland is... (2012) PLUS FERTILITY RATE! ...weird that whites have a high one!
96.9% WHITE; 2.16
-87.9% Irish; 2.12
-5.0% British Isle White; 2.03
-2.0% Polish; 3.76
-1.0% Former USSR; 1.87
-0.7% American, Australian, South African, or Canadian; 1.56
-0.2% Other; 2.03

Irish people are Caucasian. Irish people are mainly of Celtic and Norman origin, but there have been many other influences, like the vikings. Ireland today has a wide range of nationalities in the country, from other parts of Europe, and all other continents.

Second opinion: Most are of descended from "ethnic Irish", a group of Gaelic Celts. Vikings, Normans, Scots and English have all mixed in with this native ethnic group, contributing to the population of Ireland today. There are some Scots-Irish in the Republic of Ireland, but they mostly live in Northern Ireland. Another native ethnic group are the Irish Travellers, a group of Roma, or Gypsies.
There are also the descendants migrants from other parts of the United Kingdom, as well as Europe and Asia (such as Poles, Indians and Chinese). Ireland's predominant immigrant groups are similar to the UK's, but Ireland is far less diverse than England is.
As with any country, the Irish are a mix of many nations over thousands of years. Modern day Irish people have origins from many countries. There is a north European influence from the Viking era, a Spanish influence going back thousands of years to the first inhabitants of Ireland and there is the Celtic influence and British influence. In recent times people from many countries have come to live in Ireland and in time they too will make their contribution to becoming the Irish people of the future.
In terms of the historical origins of Ireland, the very first people came from northern Spain. Celts also came, but were not the first as some people think. There are people of Scandinavian origins through the Vikings. There are people of Norman origins. In terms of modern Ireland, most people are white Irish. There are a large number of white people from other countries, mostly other European countries. There are a lot of African people in Ireland. There are a lot of Asians, particularly from China, but also other countries in Asia.
