Updated on Monday (12/17) morning, below are 8 slides covering (click on any slide for larger version):

1. Voting results: 57% said YES in Round 1
2. Projections for Round 2: Expected 30% turnout with 64% YES vote - yielding overall result, across both rounds, at 60% YES
3. Participation Rates: 32% in Round 1 - pretty low
4. Detailed/underlying data (any corrections welcome)

1. Voting Results

The voting results are compiled from the Ikhwan website (given their accuracy in presidential elections, I will use their voting data for now).  The registered voters for this referendum comes from Egypt Independent.  All other data comes from previous analyses that can be found sourced elsewhere on the website.

2. Projections for Round 2 (and more detailed results)

The below is my humble attempt at just making projections based on historic data so it obviously does not isolate certain factors that may have existed during one election vs another - more importantly, it does not factor any effects that may have taken place since the presidential elections through today and/or any effects that on the ground campaigning may have over the coming week.

It really does not entail much more than taking data and extrapolating it so take it at face value but it is interesting in either of two cases:

1. If it is right: Then we are starting to see some voting trends across governorates and parties can begin to capitalize on this and target campaigns.  Or, I just got lucky and it was some other factors/data/variables.

2. If it is wrong: Then we see deviations in Egypt's voting across the elections and it illustrates changing tendencies and fluid loyalties.  Or, my methodology/analysis was flawed.

The biggest caveat of all the analysis on this website (thus far at least) is that it is based on governorates level data and results.  For example, in Cairo there are 43 marakiz which would allow for a much more granular analysis.

Slide 3: For governorates that have not yet voted, registered voter count is based on Rnd2 of presidential elections.  For governorates that have voted already, Ahram published an atricle which had their updated registerd voter count.

Slide 8: The March 2011 referendum registered voter count is based on the parliamentary election data I found on the elections.eg website. I have not been able to find registered voters for the Mar-11 referendum, and have been told there isn't one but please let me know if you have it.
CURRENT STATUS: 110,000 votes counted with 50% YES and 50% NO - however, Alexandria plays largely in these figures! Removing ALEXANDRIA gives you 65% YES....

Attempting to compile all the referendum results as they come out and, with @weskandar's great idea to cross-tab those with reported violations and see if there is trends/correlations between %YES VOTE and reported violations. 

Below is a VERY preliminary tally of vote results, just setting up and will continue to add ligan as they come in but have already started building on the below.  (Additionally, here is a governorate level spreadsheet that will be filled out - likely faster than I can do mine)

Update 1 (11PM): Apparently, only 16,000 votes have been announced so far - so the below should be about 25% of publicized results 

Update 2 (11:30PM): Reports that 40,000 votes have been announced so far, with around 75% voting "YES"
UPDATE: Day Two "Exit Poll" Results

I will continue to post as the exit poll results come out then switch to another post to aggregate preliminary voting count results as apparently the FJP/MB organization 

1. Moussa Campaign from Twitter: Claims very close race between Morsi and Moussa (obvoiusly within the margin of error, although they don't have details on their figures to confirm that).  Moussa campaign is claiming that exit polls "are conducted by representatives in 13,000 polling stations in all governorates."

2. AlJazeera Arabic: Exit polls have a four way very close race (all of them within margin of error I would assume).  According to Jamal El Shayyal at AlJazeera the polling included 60,000 people...

Both figures are below... But again, keep in mind the exit polling industry is nascent (was somewhat of a trivial endeavor in Mubarak days) so take these results with skepticism...

So below are comparisons of three different “exit poll” (very loose use of the word!) results that I have come across this morning… See below for tables and details (click on images below the text for larger versions and links are provided to all original sources through highlighted red ink & aggregated pre-elections polls can be found here)

1.   Amr Moussa Campaign: Morsi, Moussa, Fotouh, Sabbahy, Shafiq
2.   Guy with Hala Sarhan on her show: 3 guys neck and neck, Moussa has no chance
3.   @Sandmonkey: Sabahi, Fotouh and Shafiq neck and neck then Morsi then Moussa
4.   “Rights & Citizenship Center” : Morsi & Fotouh tie, then Shafik, then Sabbahi & Moussa tie
5.   @FJPartyOrg : Corroborates Morsi lead but won't release results til after polls close

So numbers 1, 2, 4 and 5 all have Morsi in the lead or tied for it but other percentages vary. 

For Moussa Campaign polls Moussa comes in second place, while the other polls have him faring very poorly.  The "Rights and Citizenship Center" has Morsi and Aboul Fotouh tied with Shafik 

While I have never heard of them before, The "Rights and Citizenship Center" has some details of who leads in which governorates- will paste below as well. (Also, where they polled specifically)

Hala Sarhan guy (apparently from Al-Ahram center) doesn’t specifically state who is in the lead – just that Moussa is doing poorly, specifically “that Amr Moussa has no chance of winning” and that there are three people who are neck and neck in the race – Shafiq, Sabbahi and Aboul Fotouh.  

The above polling seems to corroborate with @Sandmonkey’s – as his article states :” Abol Futouh, Hamdeen & Shafik neck & neck at the top of the race. Then Morsi and fifth comes Amr Moussa.”  However, the pollster on the Hala Sarhan show did not explicitly mention that Morsi was doing poorly - just that three were neck and neck, while Moussa is doing poorly - so while not corroborating Sandmonkey's Moussa conclusion, it does not negate it per se.

Obviously the methodologies are not disclosed (guy in video mentions something about 3,000 phone calls but I believe that applies to the pre-election polling they were doing – unclear).

No official results will be announced until next week, and the early releases could be politically motivated (i.e. intended to influence the vote).

Moussa polls disclaimer: The percent of “others” was not stated in the first poll in the stayed the same as the second polling.

Participation rateshttp://www.egyptindependent.com/news/live-updates-candidates-cast-their-ballots

Abu Bakr al-Guindi, head of the Central Agency for Public Mobilization and Statistics (CAPMAS), estimated that the projected turnout of the presidential election will be roughly 60%, based on voter behavior on Wednesday.

Guy in Hala Sarhan video claims that participation rates was 12% of registered voters for the first day.

UPDATE 2 (Monday evening): There are a total 590,838 registered voters on the official election website and the countries that are included in the below figures account for 575,004 registered votes (i.e. the data accounts for 97% of registered voters).   The below's analysis includes vote tally of 296,232 yielding an overall participation rate of 50.1% - of registered voters.

That leaves only 11,798 registered voters remaining and, assuming an equal participation rate, would translate into 5,915 votes - which are relatively insignificant so the below can be taken as final results.  (Click on image below for much larger version).

Country by country data comes from @hany2m's Google Docs spreadsheet here
@hany2m has a great spreadsheet that provided the underlying data - country by country - for the above (http://ow.ly/b2H0Q)

UPDATE 1 (Sunday evening):
Results from Jeddah have been published here (seems pretty valid to me) - hence, I have provided an updated chart... (The actual percentages of votes by candidate are likely slightly lower as I have not included the less successful candidates in the analysis in the interest of time - these should not substantially impact the percentages though)
Older results below:

There was not much discrepancy in the voting percentages based on the socio-economic status.  The biggest discrepancy seems to be between extreme vs middle socio-economic groups (i.e.  the "rich" and "very poor" categories voted relatively similarly while the "middle one", "middle two" and "poor" categories voted relatively similarly).

The strongest area where this held true was in Wafd voting - where the "rich" and "very poor" voted at about half the percentage as the other groups.  The above correlation seemed to hold true for Islamic vs Secular and for percent voting for liberal parties, albeit weaker.

The only real discrepancy in this was with regards to Salafi vs Non-Salafi votes in which the "rich" group was clearly outstanding when compared to the rest (-10% salafi). 

Analysis of voting orientation based on demographics
  1. Islamic vs Secular voting breakdown by district wealth
  2. Breakdown of Islamic Vote (Salafi vs Non-Salafi)
  3. Breakdown of Secular Votes (Liberal vs Felool vs Wafd)

The voting districts were classified into socio-economic groups based on the work of Ahram Center and DEDI to classify the voting districts into socio-economic groups including "rich", "middle one", "middle two", "poor" and "very poor" based on:

• Share of 15-44 year olds
• Share of illiterate
• Share of university and above graduates
• Share of unemployed
• Share of public sector workers

Then, political parties were coded based on their orientation (see table)
