Facebook total user count - facebook

Does Facebook have an API method that displays the total number of users registered on the website? Or is there any way to get a live tally of this information?

This isn't publicly available data, the only information is on the press site. https://www.facebook.com/press/info.php?statistics

Is there a way to count the number of times each individual Facebook Friend has liked your Facebook posts?

Iam trying get the number of times each individual liked my particular post.
It seems that it is possible to get the overall like count of a page.
But I dont need the overall like count. I want in specific data of a user who liked my posts.
I tried these links
How can I get fan page likes count using graph api?

How to get Facebook likes count for a Facebook page?
I am just writing the answer which is mentioned in the comment. Because that's the answer.
No, that is not really possible. Each of your friends would have to
sign in to your app and grant it permission to read their likes, and
you would need to have valid individual user tokens available for all
of them each time you want to request this data, because “A User or
Page can only query their own likes. Other Users' or Pages' likes are
unavailable due to privacy concerns.”

Facebook total Reach with insights API

On Facebook Insights UI there is a section called "Reach".
Using page_impressions_unique of Insights API (which is supposed to carry the "Reach" value) I get a value which is 1/3 of the one appearing on UI. It seems they add some other metrics but it's not clear how to get that very same value using page metrics from Insights API.
https://developers.facebook.com/docs/graph-api/reference/v2.8/insights
Does anyone have any clue about it?
Reach in Facebook Ads Manager does not equal page_impressions_unique or even contain it. page_impressions_unique is a form of non-advertising, organic reach for your page; namely people who visited your page based on non-ads activity on Facebook.
Reach in Ads Manager is the number of unique ad impressions that Facebook delivered to people.

How to get number of like, share, comment of post of Facebook, Instagram and Twitter?

I am making ios and android apps and I want to get number of likes, shares, comments of any post that is posted by particular user from his/her Facebook, Instagram and Twitter accounts.
Means how can we get number of like, share, comment of the particular user's post of Facebook, Instagram and Twitter?
Does Facebook, Instagram and Twitter APIs/SDKs support this?
Please provide any reference link to achieve this.
I'm not sure about twitter or instagram API's but facebook graph API allows you to do this, given that you have the necessary permissions.
You can always check the public data, your own posts and such..if you want to have access to the data of a particular users feed/posts they will need to provide you with that permission. (user_posts in this case)
As for the total count you can retrieve it by adding .summary(1) to the end of your query ex. for likes, comments and shares.
me?fields=posts{comments.summary(1),likes.summary(1),shares}
you can also limit the number of comments/likes/shares to zero so that you retrieve only the total count per post. If that is what you want simply ad .limit(0) before the .summary(1) ex. comments.limit(0).summary(1)
Shares however are different from comments/likes/reactions, you can only retrieve the count of shares from graph API therefore you do not need to provide anything other than the "shares" query to the post to recieve that.
Cheers!

can Fans email be extracted from Facebook using the api?

using the Facebook API it was possible to extract your friends list, is this true of a Fan page you are the administrator of?
No, you cannot pull a list of 'likers' for a given fan page, only the the fan_count which returns the total number of likers. You can see the list of connections for the Page object here.

How to display a list of Facebook users registered with my Facebook Connect website

I'm developing a website using Facebook Connect as the only membership/authentication mechanism.
So far authentication and inviting friends work.
Now I'd like to display a list of users registered with my Facebook application. Something like : "There are 1234 members in the AppName community" + a list of profile pictures.
How would I do that ?
Thanks !
This is actually pretty easy to do. After each user connects with your site through Facebook Connect, create an entry for them in some user table (which you're probably already doing). Then when a user logs in simply display the total number from your users table and randomly select 10 user IDs (or whatever number of pictures you want to display) and show them using the FBML <fb:profile_pic> tag http://wiki.developers.facebook.com/index.php/Fb:profile-pic.
There is some metric information available about your application via the Admin.getMetrics API call. I believe it only provides the number of active users within a certain time period however.
The actual total number of users is difficult to track due to people who remove the application, or might have it installed but blocked. I don't think it's available as a specific property anywhere. The information pages about Facebook apps never show the total number of users, only the monthly active users, which is what Admin.getMetrics() can tell you.
