• [The totals given here are the sum of all valid ballots cast in each constituency, and the percentages are based on such totals. The turnout percentages in the last column, however, are based upon all ballots cast, which also include anything from twenty to a thousand invalid ballots in each constituency. The total valid ballots' percentage of the eligible electorate can correspondingly differ by 0.1% to 2% from the turnout percentage.]

• Independent Unionist vote in 1998 (2.8%) included in the Independent column (not "others"). TUV = Traditional Unionist Voice.

Out of the 22 candidates from the seven parties which won no seats in 2011, the four candidates who won more than 1,000 first-preference votes (and more than 4% of the total first preferences) in their respective constituencies were:

1. Eamonn McCann of the People Before Profit Alliance in Foyle: 3,120 (8.0%),
2. Henry Reilly of the UK Independence Party in South Down: 2,332 (5.6%),
3. Gerry Carroll of People Before Profit in Belfast West: 1,661 (4.8%), and
4. Brian Ervine of the Progressive Unionist Party in Belfast East: 1,493 (4.6%)[15]

Three-fifths, or 8,606 (60%), of the 14,338 first preferences cast for the seven minor parties went to these four candidates.

Of the 15 independent candidates, running in 9 separate constituencies, the 8 who won more than 1,000 first-preference votes (and over 2.5% of the first-preference total) were:

1. David McClarty, MLA, formerly Ulster Unionist, re-elected in East Londonderry: 3,003 (8.6%),
2. Alan McFarland, MLA, formerly Ulster Unionist, defeated in North Down: 1,879 (6.7%),
3. Alan Chambers, also losing in North Down: 1,765 (6.3%),
4. Dawn Purvis, MLA, formerly Progressive Unionist, defeated in Belfast East (see above): 1,702 (5.3%),
5. Paul McFadden in Foyle: 1,280 (3.3%),
6. Raymond McCord in Belfast North: 1,176 (3.5%),
7. Paddy McGowan in West Tyrone: 1,145 (2.9%), and
8. Eugene McMenamin, also in West Tyrone: 1,096 (2.8%)

A majority (8,395 or 54%) of the 15,535 first-preference votes cast for independents went to the first four of these candidates, three of whom had been elected by other parties in 2007. David McClarty was the only successful independent candidate.

• The Alliance gained a seat in Belfast East (from Dawn Purvis, an independent elected as a Progressive Unionist). Net gain +1.
• The Democratic Unionist Party gained seats from the UUP in Belfast North and North Down, but lost one to the UUP in Strangford. The DUP also gained seats in the Lagan Valley (from SF) and South Antrim (from SDLP), but lost a seat in West Tyrone (to UUP or SDLP). Net gain +2.
• An independent elected in 2007 from West Tyrone did not run again in 2011 (seat won by SDLP or DUP). An Ulster Unionist elected in 2007 from East Londonderry, who was not re-nominated by his party, won election in 2011 as an independent. (After his re-election, he decided to remain an independent outside the UUP.)[16][17] Three other independents elected in 2007 by different parties were not returned in 2011: a former Ulster Unionist in North Down (to DUP), a former Progressive Unionist in Belfast East (to Alliance), and a former Sinn Féin member in Fermanagh & South Tyrone (regained by SF). No net change from 2007; net change from the outgoing Assembly: –4.
• The Progressive Unionist Party elected a single member in 2007 from East Belfast who resigned from the party in 2010 (and whose seat was gained by the Alliance in 2011). The PUP failed to elect its only candidate in 2011. Net change from 2007 –1; no net change from the outgoing Assembly.
• Sinn Féin gained seats in East Antrim (from UUP) and Fermanagh & South Tyrone (from SDLP), but lost one in the Lagan Valley (to DUP). It also regained a second seat in Fermanagh & South Tyrone that had been held by an independent originally elected as Sinn Féin. Net gain +2 from the outgoing Assembly and +1 from 2007.
• The Social Democratic & Labour Party gained a seat from West Tyrone (from Ind. or DUP) but lost seats in Fermanagh & South Tyrone (to SF), North Antrim (to Traditional Unionist Voice) and South Antrim (to DUP). Net loss –2.
• Traditional Unionist Voice won its first and only seat, in North Antrim (from the SDLP). Net gain +1.
• The Ulster Unionist Party gained seats in Strangford (from DUP) and West Tyrone (from DUP or Ind.), but lost seats in Belfast North (to DUP) and East Antrim (to SF). Another two members elected as Ulster Unionists in North Down and East Londonderry left the UUP before the 2011 election. Net loss from 2007: –2. (No net change from the outgoing Assembly.)

Several of the 14 members who retired early from the Northern Ireland Assembly did so either after being elected or re-elected to the British House of Commons on 6 May 2010 (as MPs), or else in anticipation of being elected to the Dáil Éireann (lower house of the Irish parliament) on 25 February 2011 (as a TD). [Three retired or retiring members are Privy Counsellors of the United Kingdom (PC).]

These are the 25 changes in membership that occurred between the third Assembly's dissolution in March 2011 and the fourth Assembly's election in May. Seventeen sitting members did not present themselves for re-election and another eight were defeated at the polls. One re-elected member had been elected with a different affiliation in 2007.

The numbers indicate the percentage of votes each member received in the first round of counting under the Single Transferable Vote in the 2011 election, and the round which decided his or her election or defeat.

In some constituencies (Foyle, West Tyrone and Fermanagh & South Tyrone), it is not possible to couple a single outgoing member by party with a single successor. The pairs of outgoing and incoming members in those seats are presented in arbitrary order.

Most of these changes occurred due to a member's retirement, although one defeated member of the SDLP, in Foyle, was succeeded by another member of the SDLP.

Note that the party changes in Lagan Valley, Strangford and East Antrim cancelled each other out.

David McClarty, originally elected from East Londonderry as an Ulster Unionist, although not re-nominated by the UUP in 2011, stood successfully for re-election as an independent. This reduced the UUP's strength from 2007, while keeping independent strength in the Assembly at one (as Kieran Deeny, the retiring independent member, was not succeeded in West Tyrone by another independent). McClarty decided not to re-join the UUP after his re-election.[17]

European Union (EU) and Commonwealth citizens aged 18 or over on election day were entitled to vote. The deadline for voters to register to vote in 5 May elections was midnight on 14 April 2011. All voters had to present one piece of photographic identification in order to cast a vote at the polling station: accepted forms of ID were an Electoral Identity Card, a photographic Northern Ireland or Great Britain driving licence, a European Union member state passport, a Translink 60+ SmartPass, a Translink Senior SmartPass, a Translink Blind Person's SmartPass or a Translink War Disabled SmartPass.[20] Voters who didn't have an accepted type of photographic ID had until 22 April 2011 to apply for an Electoral Identity Card from the Electoral Office. A judicial review brought by candidates in the simultaneous local government elections, challenging the non-acceptance of EU national identity cards as a proof of identity, failed on 4 May 2011.[21]

In the days following the 2011 Assembly election concerns were raised by politicians and others about the time it took for ballots to be verified and counted. The first result came in at 7:00 p.m. on Friday 6 May, nine hours after counting began and 21 hours after polls closed.[22] The announcement of the final results for some constituencies came two days after the polls closed. In contrast, the first result for elections held in Scotland on the same day as the Assembly election came in at 12:54 a.m., just under three hours after counting began, and the final result came in at 5:21 p.m. on the same day (Friday 6 May). In response to the criticisms about the speed of counting, Northern Ireland's Chief Electoral Officer, Graham Shields, defended the process, saying that it was "about accuracy, not about speed", adding that "This is a complicated process and people have to accept that. We will take as long as it takes to get it right."[23]
