The figures, gathered from official government sources by the anti-settlement monitoring group Peace Now, show an increase in building in 2018 and a sharp spike in planning for future construction.
The trend, highlighted last week when an Israeli committee advanced plans for thousands more settlement homes on occupied lands, has only deepened Palestinian mistrust of the Trump administration as it says it is preparing to roll out a Middle East peace plan.
Each new settlement expansion further diminishes the chances of setting up a Palestinian state alongside Israel.
Both supporters and opponents of settlements confirm a change in atmosphere since early 2017 when Trump took over from Barack Obama, whose administration had tried to rein in construction.
"The feeling of the [Israeli] government is everything is allowed, that the time to do things is now because the [US] administration is the most pro-settlement you can ever have," said Hagit Ofran of Peace Now's Settlement Watch program, AP reported.
Peace Now uses several measurements of settlement activity. These include "plans", or the early bureaucratic stages of preparing a project, "tenders", when bids are solicited from contractors to do the work, and "construction starts", when the building actually begins.
Each of these figures tells a different story. While construction starts give a snapshot of the current level of settlement activity, they reflect decisions made years ago. In contrast, the planning and tender stages are seen as forward-looking indicators of a government's intentions.
Highest level of planning since 2013
The data compiled by Peace Now showed a drop in construction starts during Trump's first year in office, to 1,643 units in 2017 from 3,066 units the previous year. This drop appears to reflect the lingering effect of reduced planning during the final two years of the Obama administration.
But the data for the first nine months of 2018 indicates the beginning of a Trump effect, with construction starts 20 percent higher than the same period a year earlier.
These trends are even more evident when looking at the planning process. In 2017, plans were advanced to build 6,712 new settlement homes, roughly 2.5 times the 2016 level.
In 2018, plans for an additional 5,618 units were advanced, nearly half of which were processed last week alone.
Together, these numbers are the highest level of planning seen since 2013. At that time, Israel pushed forward settlement construction to counter criticism of its release of Palestinian prisoners as part of then-Secretary of State John Kerry's peace efforts.
The biggest surge in settlement activity during the Trump era is in tenders - projects that are ready to be launched.
In 2017, 3,154 tenders were issued, up from just 42 during Obama's final year in office. In 2018, that number rose to over 3,800, the highest number by far since Peace Now started compiling the data in 2002.
This sets the stage for a huge jump in construction in the near future.
"There's definitely a change of atmosphere. There's definitely a change of winds," said Oded Revivi, mayor of Efrat, a major settlement near Jerusalem, and the chief foreign envoy of the Yesha settlement council.
Revivi said that Obama pressured Israel into greatly curtailing settlement activity. Now, he said, Israel is trying to make up for lost time.
"Basically, what you're seeing now is the statistics are trying to catch up to the needs that were built up during the eight years of the Obama administration when everything was in a standstill," Revivi said.
White House Middle East envoy Jason Greenblatt's office declined to comment, and State Department officials were not immediately available for comment.
Palestinians and most of the international community consider Israeli settlements to be illegal and obstacles to peace. Over 400,000 Israelis now live in the West Bank, in addition to 200,000 in occupied East Jerusalem (Quds). The Palestinians seek both areas, captured by Israel in 1967, as parts of their state.
For decades, a string of US presidents, both Republican and Democrat, condemned settlement construction.
Things quickly changed when Trump took office. Trump refused to condemn settlement construction and surrounded himself with advisers - including his son-in-law Jared Kushner and Ambassador to Israel David Friedman - who are Orthodox Jews with close ties to settlements.
Trump at times has asked Israel to show restraint, but his administration has remained largely silent as Israel has pressed ahead with its construction efforts over the past two years.
This has been welcome news to Prime Minister Benjamin Netanyahu, whose outgoing right-wing coalition is dominated by religious and nationalist settlement sympathizers. Favored to win re-election in April, Netanyahu has said he expects his next government to look very similar.
